UC560 and pop3 issue

[gdamjanovic]

Hi all,

I am deploying UC560 on my customer site. I alredy wrote about pppoe problems. now i have new isue with clients inside network when trying to get mail from their pop3 server and getting errors. I noticed that when i set firewall on low setting problem disaperes. I also noticed that issue is present with MS outlook 2010 (2007 works fine). does anybody have idea how to setup firewall to bypass pop3 traffic when setup on midium.

BR,

Goran

Firewall on Cisco is known to cause problems of many kinds.

If you use NAT, you don't need firewall. You can disable it completely and there is no security risk whatsoever.
