IPSec LAN-LAN Full Tunnel
I have an IPSec IKEv2 LAN-LAN VPN configured on my ER605 (initiator). It functions as expected, and I'm able to bi-directionally access devices on each side of the VPN.
On my Initiator side, I'd like to route all traffic through the VPN tunnel. By default, it routes all public-bound traffic through the Initiator's WAN, but I need it to go through the VPN to the Responder's WAN and out through there.
I have tried the following:
- My IPSec IKEv2 VPN doesn't appear as an option under Policy Routing, so I can't use that
- I tried a static route for 0.0.0.0 (mask 0.0.0.0) with next hop as the Responder router's IP, and tried with both LAN and WAN interface, but it says "Invalid Parameters".
- I tried setting my Responder router's IP as the "Default Gateway" for my Initiator's DHCP settings, but that kills all connectivity outside of the LAN.
What am I missing here? How can I achieve this? I can't imagine that a business VPN router wouldn't have a way to route all traffic through the VPN, as that's an important feature for any business network.
