Hello, I have following config.
WAN: x.x.x.7/24 GW: x.x.x.1
LAN: 172.16.0.1/24
Then I have followed https://www.thomas-krenn.com/en/wiki/OPNsense_WireGuard_VPN_for_Road_Warrior_configuration (https://www.thomas-krenn.com/en/wiki/OPNsense_WireGuard_VPN_for_Road_Warrior_configuration) tutorial and it works as intended.
OPNsense wg0: 10.10.0.1
Peer wg0: 10.10.0.2
Only change I made is the peer's allowed IP is 0.0.0.0/0. Now OPNsense routes through this peer.
Now I'd like LAN clients to route through Wireguard Peer.
Basically users from LAN: 172.16.0.50->172.16.0.1->10.10.0.2->0.0.0.0/0
How can I do this?
Basically do this (I think - I cannot find my notes on how I did this):
1. System > Gateways > Add gateway.
Name can be 'GW_WireGuard' - the interface selected would be your WG interface.
2. Make a rule on the LAN interface; expand the ruleset (advanced or something) and select your newly created gateway instead of the default gateway.
Maybe this can get you started?
