Hi!,
we have problems with Messenguer and NAT. I think that Messenguer uses a protocol not very robust base to a SSL (443) TCP session. The problem is
that out CISCO internet router is configuring with NAT with a tcp-timeout of
60 seconds because of serveral questions. So when a user is not
generating traffic the tcp NAT timeout removes the session. After that
user must reconnect Messenguer.
I think that with the following command perhaps could solve the problem:
"ip nat translation port-timeout tcp 443 never"
After some tests we have noticed that router always applied the timeout that
is configured in the command "ip nat translation tcp-timeout 60".
Is it a normal behaviour? is a bug? Any ideas how can i solve the problem?
CONFIGURATION
ip nat translation tcp-timeout 60
ip nat translation port-timeout tcp 443 never
ip nat pool POOL-PUBLICO X.X.X.X X.X.X.Y netmask 255.255.255.0
Thanks!
