I have a 827 router going out to the inter net via a dsl line. I can get to the pop3 server but can not send mail to the smtp server. I was told that I should open port 25. I am not sure how to do that. This is the 1st time I am working with a router. Is there a way to look at the current settings on the router so is I mess things up I can set it back to the way it was.
Thanks for any help
