Skype for business over Check Point Firewall

Hi MatesI need an urgent help.Has anyone has implemented skype for business over a Check Point Firewall?I am trying to do so, but I am having issues with certificates presented to mobile devices (smartphones, tablets) when connecting to our internal SFB servers. The internal servers are present a self-signed certificate, hence they clients are unable to connect.Thanks in advance

Move External Interface to different NIC

Gaia 3.10 R80.20 fail-over cluster using ClusterXL on Open Servers (Dell R740).  I need to move the External interface from a 1G copper (eth2) NIC to a 10G SFP+ slot (eth0) utilizing a DAC cable.  Here is my plan so far:Do during a maintenance window as there will be an outage:Via CPUSE, Network Interfaces tab;  Start on Standby member delete IP address from eth2 and disable NIC.  Configure eth0 with settings & IP from eth2, disable auto-negotiation, click on link speed and select 10Gbps / Full and enable NIC.   Then do Active member (which will start my outage).  Disconnect copper cables from eth2 and connect DAC cables.Via SmartConsole, edit FW Cluster object, select Network Management; copy all info from eth2, then delete the eth2 interface.  Then should I :    a.)  Do a "get interfaces with topology"  OR    b.)  Add a new interface and input the info from eth2 by hand. I'm thinking I should do the "get interfaces with topology" just worried it might change some settings or something with the other interfaces....Then, save and push policy.  Or do I need to reboot the gateways first?  Since there isn't a discntd.if file anymore I don't think I need to reboot them.... PLEASE let me know if I'm missing something or if there is a better way to do this.

First impressions R80.30 on gateway - one step forward one (or two back)

Ok, we were finally "forced" to go ahead and upgrade our gateways from R80.10 to R80.30 for fairly small things - we wanted to be ale to use O365 Updatable Object (instead of home grown scripts) and improve Domain (FQDN) object performance issues when all FWK cores were making DNS queries causing a lot of alerts (see Positive things - upgrades were smooth and painless - both on regular gateways and VSX. All regular gateways seems to be performing as before, but I have to be honest that they are "over-dimensioned" and having rather powerfull HW for the job - 5900 with 16 cores. VSX though threw couple of surprises. SXL medium path usage. CPU jumped from <30% to above 50% on the busiest VS that only has FW and IA blades enabled. Ok, there is also VPN but only one connection:             I haven't spent enough time digging into it but for some reason 1/3 of all connections took medium path whereas before in R80.10 it was nearly all fully accelerated. And most of it was HTTPS (95%) with next most used LDAP-SSL (2%) I used the SXL fast accelerator feature (thanks @HeikoAnkenbrand to exclude our proxies and some other nets and you can see that on friday CPU load was reduced by 10% but nowhere near what it used to be. I just find it impossible to explain why would gateway with only FW blade enabled start to to throw all (by the looks of it) traffic via PXL. And statistics are a bit funny too:   FQDN alerts in logs. I can definitely confirm that only one core now is doing DNS lookups (against all DNS server you have defined, in our case 2). But we are still getting a lot of alerts like these: Firewall - Domain resolving error. Check DNS configuration on the gateway (0)             Especially after I enabled updatable object for O365 in the rulebase. As said before - I have not spent too much time on this as we had other "fun" stuff to deal with on our chassis, so it's fairly "raw". I will report more once I had some answers

Gateway issue post upgrade to R80.30

Hello all,I recently upgraded my SMS server from R80.20 to R80.30 and ran all pending hotfixes after the update.  I took new backups of the config and snapshots of the SMS server after all was done.  I then started the snapshots and backups of the one and only gateway that we utilize.  I ran the upgrade from CPUSE.  After it rebooted the management interface never came back up.  The device was located off site at a data center so I had to go capture it and it is now on my desk.  I can connect to the device CLISH from console but I have no idea how to troubleshoot what went wrong or how to proceed with the upgrade to the R80.30 version after this failure.  Luckily this is not in production yet.  We are still on our old firewall systems until I get this online and working in R80.30.  Can anyone point me in the right direction? Tim

ONELINER - process utilization per core

With this onliner you can view the process load of each core. Change the variable CORE to the correct core number (for example CORE=3):   CORE=3; ps --sort=-c -e -o pid,psr,%cpu,%mem,cmd | grep -E "^[[:space:]][[:digit:]]+[[:space:]]+${CORE}"   ps L -> List all format specifiers (for example pid, psr, %cpu, %mem, ...) There is still much potential for improvement here 🙂

My ISP has been compromised. And no idea what to do?  ISP has been already compromised few months back but i thought my router is from local company therefore such issue. But i am wrong. I have use the another router and even firewall. All become waste for me. Firewall fail to stop.  I have send the report to Kaspersky. And kaspersky says the problem from router side. And when i search in google. Some developer says it is from ISP side. I have format my system 3 times, reset router , reset firewall. All become failure.

R80.x Performance Tuning Tip - Elephant Flows (Heavy Connections)

Elephant Flow (Heavy Connections) In computer networking, an elephant flow (heavy connection) is an extremely large in total bytes continuous flow set up by a TCP or other protocol flow measured over a network link. Elephant flows, though not numerous, can occupy a disproportionate share of the total bandwidth over a period of time.  When the observations were made that a small number of flows carry the majority of Internet traffic and the remainder consists of a large number of flows that carry very little Internet traffic (mice flows). All packets associated with that elephant flow must be handled by the same firewall worker core (CoreXL instance). Packets could be dropped by Firewall when CPU cores, on which Firewall runs, are fully utilized. Such packet loss might occur regardless of the connection's type. What typically produces heavy connections: System backups Database backups VMWare sync. Chapter More interesting articles: - R80.x Architecture and Performance Tuning - Link Collection- Article list (Heiko Ankenbrand) Evaluation of heavy connections The big question is, how do you found elephat flows on an R80 gateway? Tip 1Evaluation of heavy connections (epehant flows)A first indication is a high CPU load on a core if all other cores have a normal CPU load. This can be displayed very nicely with "top". Ok, now a core has 100% CPU usage. What can we do now? For this there is a SK105762 to activate "Firewall Priority Queues".  This feature allows the administrator to monitor the heavy connections that consume the most CPU resources without interrupting the normal operation of the Firewall. After enabling this feature, the relevant information is available in CPView Utility. The system saves heavy connection data for the last 24 hours and CPDiag has a matching collector which uploads this data for diagnosis purposes. Heavy connection flow system definition on Check Point gateways: Specific instance CPU is over 60% Suspected connection lasts more than 10s Suspected connection utilizes more than 50% of the total work the instance does. In other words, connection CPU utilization must be > 30%   CLI Commands Tip 2Enable the monitoring of heavy connections. To enable the monitoring of heavy connections that consume high CPU resources: # fw ctl multik prioq 1 # reboot Tip 3Found heavy connection on the gateway with „print_heavy connections“ On the system itself, heavy connection data is accessible using the command: # fw ctl multik print_heavy_conn Tip 4Found heavy connection on the gateway with cpview # cpview                CPU > Top-Connection > InstancesX   Links sk105762 - Firewall Priority Queues in R77.30 / R80.10 and above
