I have 2 RB2011 routers setup with a IPSec Site-to-site, no problems with connecting.
The problem is that i can ping back and forth from both sides, but when i try to access other data across the tunnel, for example the web interface of a VoIP phone, nothing really happens, wireshark shows that i dont get any data.
Chrome error message is ERR_EMPTY_RESPONSE
Sometimes, but very rarely do I get a reply but it only works for a few seconds. Seems like this concurs when the IPSEC "re-authenticates" but im not sure.
