I've got the VPN to connect a few times, but after a day or so it drops and will not re-connect without power cycling everything.
I'd like to get this up and fully stable.
Tried disabling firewall completely on both routers - no help.
Block WAN is NOT on in either end.
Both routers have a public IP - no NAT
Tried forwarding IPsec traffic - no help.
Advanced routing is on, set to Gateway on both end.
using IKE with prehsared key (tried using different keys many times)
Multicast passthough is on both at firewall and at VPN config levels.
both ends have aggressive mode and keep alive active.
Set both ends to Smart LInk backup and turned off network detection in all WAN settings.
Both routers are running FW: v1.5.1.05 (2019-10-01, 15:39:40)
