All port forwarding not working occasionaly (inc admin access and sslVPN) while ping works

[Yaakov132522]

So, the client had cameras installed and asked us to forward ports.

He complained they didn't work so I used nmap on the checkpoint and sometimes got good results and sometimes bad ones. didn't see any dropped packets in the logs or any packet loss through the ISP.

So I ran an nmap script and a ping test at the same time for a few hours and it seems that the ports go on and off all the time for no apparent reason but the weird thing is, when I got bad result, at the same time I had no loss at all with the ping test, and still, I didn't find anything interesting in the logs.

Any Ideas what it could be?

I believe it's a checkpoint SMB 1530 or 1550

2 things that come to my mind are maybe IPS (if enabled) and possible connections table issue. Locally or centrally managed smb?

Eventually I did a software update and the problem was solved

I tried to do it before but it was failing but I didn't connect the dots at that point

The update is probably based on the 443 port just like the VPN port so I just had to wait till the problem was on a break to try update it

How is the "port forwarding" configured in this case?
If it's a 1500 series, you should be using Server objects.
Also, please provide the firmware version/build information.

Great news!

Also, just wondering, any specific ports that have the issue, or is it random?
