Strange issue browsing when router put into place:
Posted on 2006-05-31
Coming in on the backend of a problem that another guy was working on. Here is situation:
Remote office with VPN (just GRE tunnel) going back to headquarters. DSL connection going into router, where pppoe is setup with correct authentication and standard config taken straight from Cisco sight (and used in other locations for this customer, where everything is working hunky-dory). Nat is basic, and looks correct, and there are only three routing statements. A default going out the DSL line, where nat is on the outside interface (ie dialer in this case). Also routes for central company location going over tunnel interface.
Okay, now the weirdness. I can sit on a PC at the central company and telnet to this router fine. The strange bit has been all of a sudden the PCs cannot browse on the Internet to certain sites. Don't believe it to be DNS, because the name resolves, the page just gets stuck. That being said, I did manage to load logmein on a remote PC there (with users assistance), and my logmein session works really well, no strange speed issues, etc.
The other guy said he has run adware removal. I'm going to try going to Trend Micro this morning. The wrinkle (I'm told), is that when you take the router out of the picture, everything apparently works fine going to the Internet. They have tried multiple routers as well.
Any suggestions? I'm not in the office yet, but I will be this morning. So if you guys need to see router config I can do that.
