Cisco ASA 5505 blocking for smtp port 25?
Posted on 2013-06-11
I am new to Cisco, and do not understand command line or how to get access to it so need to do alterations via Graphical Interface. Hopefully someone can guide me :)
I have 2 mail servers
1 old that we want to remove as not supporting ssl/tls
On this one to send we use port 2225. Cisco Opens WAN:2225 to LAN:2225(spamfilter) that forwards to LAN:25(Imail)
This works fine
Now i want to setup 2nd server
I want to use port 25
so WAN:25 to LAN:25
However when setting this up in Outlook I can not get connection with port 25
The only way i can gain access is if i VPN into the Servers LAN, then use LANIP:25 it works
Therefore i concluded that fault is with cisco even through port 25 is open
Where do I start to look. Anyone has any suggestions how to PD this or how to allow port 25 through cisco using the graphical interface if thats the problem?
