Topic: Where are port forward logs kept?

[steve288]

We have been successfully forwarding ports for our exchange server.
eg
Port 110 to front end exchange
port 443 to back end exchange

This has worked great for web access.

However for some reason internally it has stopped when we use our fqdn.

My simple question is, which log file(s) will show what errors are occuring when it fails to forward.

thanks.

If packets are dropped by the firewall, they will be logged in /var/log/iptables/current. However, if you have a portforwarding problem when fqdn is used, but no problem if IP address is used, then the problem is in your domain's DNS.
