My Linksys e2500 router has been blocking (time out) incoming mail and a few specific web sites.
I can send mail no problem and browse to most pages on the web.
Email client settings are correct.
When I plug my Ethernet cable directly to my modem, I can receive emails and browse to any website.
When I turn router MTU down to 576 from 1500 it enables me to browse to a few web pages but others are still blocked and email in is still broken.
I updated to latest router firmware, reset modem back to factory defaults and did a hard button reset of router and modem. Didn't help.
