Router setup

[eviliunas]

I have a Cisco 1700 router we are about to configure

it to let e-mail come directly to us instead of

going thru our web hosting client. My question is

which ports should be open for the mail to

come and go... pop, smtp ? and also keep it secure

we do have firewall running on the router. we use

Exchange 2000 .

enable ports 25 and 110 for your mails.By Default its enabled.If you want to only enable these ports just create an access list for enbaling them only.

SMTP port 25.

Pop3 if people access there exchange box from the outside through pop
