fix for https://redmine.pfsense.org/issues/13153

[luckman212]

After downing & upping WG site to site tunnels, or stopping / restarting the service, any static routes are lost and the tunnels break if you're not using FRR/BGP etc.

This adds a call to system_staticroutes_configure() in wg_service.inc so the routes get re-added. I tested this on 22.05.b.20220512.0600 with 2 S2S tunnels and a RemoteAccess tunnel.

Thanks for the catch. Merged and synced upstream. Patch will be in next build cycle tomorrow morning.

Do you know if this has actually been resolved? I'm still having this issue. I've got WireGuard 0.1.6_2 installed, but I still need to go into Routing and manually click Save in WAN Gateway, actually, I need to do it two times, only after this Wireguard Gateway gets enabled and the WireGuard package starts up.
What's interesting is that patch introduced in 0.1.6_2 (as per https://redmine.pfsense.org/issues/12808?tab=history), doesn't seem to be applied to wg_service.inc. The line calling system_staticroutes_configure() function is missing from the file. Applying manually that patch not helping either.
I'm on pfSense 22.05.
