We have recently needed to change the router at our HQ to a cisco 2811 (Dual WAN) we were previously using an 800 series.
I have configured all interfaces and have dual adsl connections working.
I’m no expert with Vpn but as the old VPN worked I have copied the VPN elements from our old router config to the new one (just modifying the interface associations where required).
Unfortunately I cannot get this to connect. I believe that this is failing at phase 2 ? But the debug is not giving me much to go on to narrow down the cause.
The HQ has Dual WAN but only 1 VPN set up currently,
The Remote site has dual VPN, one is working the other is the VPN that we are trying to migrate to the 2811
Your advice would be much appreciated.
