I am learning how to write ACLs, and one of the exercises is that I have to write an ACL to restrict PING, HTTP, FTP, and allow POP3 and SMTP between a pc and server. Below is my ACL. The thing that does not work is the POP3\SMTP access. It continues to fail. I do not want to just add a "permit ip any any" to make it work. Can someone help? Thanks!
What port is the smtp server using? 25, 465 or 587? I would think an in house server would use 25 but most internet server use other ports. Does it work if you use permit any any? First make it work and the add remove entries to see where it breaks.
Yes the port is open for 25 and it is internal. Yes it works if I put "permit ip any any". I tried doing this line by line. But yielded the same result. If I have to do this again line by line, then what should the order be? I tried the following:
1. Just adding the "permit" lines, but no go.
2. Just addind the "deny" lines, but no go.
3. Just adding "permit" for one PC, but no go on the other PC, and vice versa.
