I have a Windows Server for SBS, and a cisco 837 router. I need to setup POP3 email access for my boss, and from my understanding the SBS includes support for this out of the box. I can see in the server management that POP3 access is enabled.
I have no formal cisco training, but i have had a look at the cisco config. I beleive i should be forwarding incoming traffic on port 110 from my external IP to my internal server's IP.
I can see in my cisco config i have the line:
ip nat inside source static tcp 192.168.1.5 110 126.96.36.199 110 extendable
which i beleive forwards tcp port 110 traffic to the server.
I also have a section in the cisco config which permits mail:
ip access-list extended ACL-Outside .... remark *** Permits Mail *** remark permit tcp any host 188.8.131.52 eq smtp permit tcp any host 184.108.40.206 eq www permit tcp any host 220.127.116.11 eq 443
but i beleive i have to add the next line:
permit tcp any host 18.104.22.168 eq pop3
Could anyone help? Will adding the above line allow pop3 mail traffic through to my server for processing? If so, how exactly do i add this to the cisco config? I know i can enter 'enable' at the terminal to show the configuration details, and also enter 'configure (...something??)' at the terminal to configure the access list, so what should be the commands i enter to add the permit tcp any host x.x.x.x eq pop3 to the cisco configuration?
Thanks in advance Simon
