I need to connect two subnets using m0n0wall as a pptp server.
There is no problem with windows pptp client, but I need any hardware 
device to use as a pptp clients.
I have tried to use many small routers - linksys (with original and open 
wrt and dd-wrt software) airlink, smc and d-link, which have pptp client 
on WAN.
No of them is able to connect with m0n0wall.
Do someone know the "small" hardware unit which works with m0n0wall or 
know some tips -how to made it works?
