Hi Mike

Here they are below.
Tinc.conf(BVPN)
Name = BVLAN996
Device = /dev/net/tap
Mode = switch
ConnectTo = WVLAN996

Tinc.conf(WVPN)
Name = WVLAN996
Device = /dev/net/tap
Mode = switch

Hosts/BVLAN996
Address = boppbvpn
Port = 665

Hosts/WVLAN996
Address = boppwvpn
Port = 665

Tinc-up for both is basically the same.
#!/bin/sh
ifconfig VLAN996 0.0.0.0
brctl addif br996 VLAN996
ifconfig VLAN996 up

Hope that helps.  But if there is anything I missed let me know.

Thanks
Brent
