error Clear text packet should be encrypted

[bezeq_int]

Yesterday we upgraded the mgmt from r80.40 to r81.20

and we have two firewalls still on r80.40

the site to site on the firewalls still up but the icmp/snmp traffic generated from same source ip addresses in the tunnel are being dropped with this error message:

@;3243628120;[vs_0];[tid_0];[fw4_0];fw_log_drop_ex: Packet proto=17 x.x.x.x:56134 -> y.y.y.y:161 dropped by vpn_drop_and_log Reason: Clear text packet should be encrypted;

@;3243632857;[vs_0];[tid_0];[fw4_0];fw_log_drop_ex: Packet proto=1 x.x.x.x:52 ->y.y.y.y:0 dropped by vpn_drop_and_log Reason: Clear text packet should be encrypted;

on the mgmt we edited this file: //opt/CPsuite-R81.20/fw1/lib/crypt.def  last lines to:

#ifndef NON_VPN_TRAFFIC_RULES
#ifndef IPV6_FLAVOR
#define NON_VPN_TRAFFIC_RULES (dst=y.y.y.y or dst=z.z.z.z)
#else
#define NON_VPN_TRAFFIC_RULES 0
#endif

the problem is still occurring

how to fix this ?

please advice

thanks

Let me see if I can find some stuff about this, it might be known issue if gateways are still on R80.40

K, found it...MAKE SURE to backup the files first, of course

# cd $FWDIR/conf

# cp user.def.FW1 user.def.R8040CMP

Thats it. Then push the policy.

No sir, that also did not fix the issue

[Expert@CP-MGMT:0]# cd $FWDIR/conf
[Expert@CP-MGMT:0]# pwd
/opt/CPsuite-R81.20/fw1/conf
[Expert@CP-MGMT:0]# ll | grep user.def

Did you install the policy?

[bezeq_int]

sure i did 🙂

[the_rock]

K, fair enough. If thats the case, I dont want to tell you to modify anything else with that file, as Im worried we may make it worse and no one wants that on the weekend lol

Anyway...maybe reverse all the changes and lets take a step back here. So, IF its saying clear packet should be encrypted, logically, that insinuates to me that something is missing in the enc. domain possibly...can you check?

Best,

Andy
