Running OSPF across a single link with an EOIP tunnel connecting the core router to an edge 2011. I tunnel my public subnet through here to make connections work.
My latest setup is behaving oddly. I have great latency and can do router to router UDP capacity tests but no TCP tests. Websites do not load. Just hang.
I have not run into this before so I am a bit befuddled as to the issue. Hoping the forum can assist in some troubleshooting. Inserted is an image of the setup all the way from the core to the edge router for your reference.
When on the tower site, I can connect to a VPN on another network and successfully gain TCP connectivity. Its just on the native public IP that I lose that capability.
Also, as expressed in image attached, I bypassed the two switches to further diagnose the trouble spot. Bringing the 2011 directly off the media converter, I get the same results.
I also used a new 2011 just in case it was hardware related there. No dice.

Update on this issue.
One oddity I have identified is that I can go to any google site. Youtube, news, Drive, +, etc…
I can ping any other site (IP or URL). But not pull them up.
All MTU (even EOIP) is set to 1560.
Seriously confused
Any insight on what I may be running into greatly appreciated.
Possibly but I now have it working by bypassing the shared switches. Its also a potential issue with the RF link as the same problem occurred on a different network using same radio models and firmware. I had to install them, then remove them when customers called in and unable to move. I have them at the office now awaiting some bench testing time. I will update this post when complete.
