It's been a while I am experiencing a problem with IPSEC.
A few weeks ago, I opened another discussion because I thought it could be a problem with GRE, but after many tests and other users suggestions, I discovered the problem is located on IPSEC phase2.
Basically, when a PPPoE interface disconnects and re-connects, the IPSEC phase2 stop working.
I made a test enviroment with one RB2011 and one RB3011.
On each RB, I have a single WAN link, and both WAN lines use a PPPoE interface. The PPPoE interface's local address is the public IP address
I am able to recreate the problem everytime I want: if I disable and re-enable the PPPoE interface on the RB3011, the phase2 stop working.
What is funny is that if I do the same on the RB2011, the phase2 doesn't have any problem.
I attached the two configurations. It's a very simple configuration, could you please take a look?
The only difference between the two setup is:
on the RB2011 the internet connection is made with a wireless link, on the RB3011 the internet connection is made with a FTTC Modem in bridge mode. But for the routerboards there should not be any difference, it should be transparent...
Any suggestion would be really appreciated...
