> 1.) Now my office LAN is 192.168.0/22, office DMZ is 10.0.254.0/24, home
LAN is 10.0.0.0/25 and home OPT1 (wifi) is 10.0.0.128/25. For the OVPN
tunnel do I need one or more separate (new) subnets to build up the tunnel
for all comination?
You should make sure to use completely new subnets for the tunnels. Make
sure that they do not overlap with anything used elsewhere.
> 2.) Can I use both IPSEC and OVPN at the same time on the same m0n0wall?
