We are using a pair of RV082 (hardware: V3, firmware: v4.1.1.01-sp) on 2 remote (symetrical) sites for:
1. site-to-site VPN using a gateway-to-gateway tunnel; and
2. remote access VPN using L2TP to a VPN Server on OS X Lion Server 10.7.3
3. VPN passthrough are all ENABLED on at both routers (for IPSec, L2TP and PPTP)
For (2), we had to setup port forwarding of IPSec (UDP/500~500) to the Lion Server (without which remote access don't work).
However, the above works except:
• we can only have IPSec forwarding enabled on 1 of the routers, 'cos when enabled on both routers, gateway-to-gateway VPN will fail to establish
• this is obviously bad as we can't have remote access VPN on one of the routers
Anyone knows why is this happening or did we miss something?
Thanks.
