Not receiving external emails after router replacement

Router configuration
I have taken over some client remotely while a fellow business owner is on vacation. I am not able to view the problems first hand because his client base is on the east coast and I am on the west. The customer called and their router went down...i.e. I can't remote in and easily fix any problem. They have purchased a new router and I have walked them through setting it up far enough to have internet. Their outgoing email through their onsite email server is working fine. They are able to send and receive email internally no problem. They however cannot receive external emails at all. I have set the POP3 port in the router. What else could have changed to not allow the receipt of external email? Thanks so much for any help...it will be greatly appreciated :)

Thanks. We'll let you know when a new response is added.

If they host there own mail server inside the network you will need to setup port 25 inbound from the internet to their email server.

    I have done this but we did not restart the router afterwards. I will double check everything in the morning. I was able to contact the other tech and now have a way to get into the system as well. Thanks for the answer!

    I am officially stumped. I have forwarded ports 110, 25, and 80 to the exchange server. I restarted the router and still not receiving external mail. The only item in the scenario that changed was the router. Would I need to reboot the server after this for some reason? They can send interoffice and they can also send mail out but cannot receive mail from external sources.

    I've solved the problem. the cable company had set their modem to the static ip when they were troubleshooting. Nothing was getting to the router in that fashion so now all is well :) Thanks Mrdenny for the comments :)
