[Shorewall-users] Shorewall bridge setup

[Hellmut T. <hel...@ro...>]

Hello everybody,

I need to bridge two different LANs with OpenVPN. According to all I read, both LAN segments need to share the same subnet. All documentation refers to examples within a /24 network.
As of now my own LAN is 10.10.1.0/24, the opposite side is 10.10.10.0/24.
To prevent the confusion that is preprogrammed by changing all IP numbers in one LAN, would it make sense to change the netmask on all clients and both gateways' bridges to /16 ? This would put both segmants into the same subnet, right?
This may be an immense waste of number space, but I doubt that I will run into IP number scarcity in this private setup :),
Any drawbacks in using such a huge netmask, maybe I miss something obvious here?

Thanks in advance,
Hellmut
