New Option: --server-nat

Traffic

How about:

--server-nat IP netmask interface

Helper directive to work as --server and add NAT rule:

For example, --server-nat 10.8.0.0 255.255.255.0 eth0 expands as follows:

 mode server
 tls-server
 push "topology [topology]"

 if dev tun AND (topology == net30 OR topology == p2p):
   ifconfig 10.8.0.1 10.8.0.2
   if !nopool:
     ifconfig-pool 10.8.0.4 10.8.0.251
   route 10.8.0.0 255.255.255.0
   if client-to-client:
     push "route 10.8.0.0 255.255.255.0"
   else if topology == net30:
     push "route 10.8.0.1"

 if dev tap OR (dev tun AND topology == subnet):
   ifconfig 10.8.0.1 255.255.255.0
   if !nopool:
     ifconfig-pool 10.8.0.2 10.8.0.254 255.255.255.0
   push "route-gateway 10.8.0.1"
   if route-gateway unset:
     route-gateway 10.8.0.2

 iptables -t nat -A POSTROUTING -s 10.8.0.0/24 -o eth0 -j MASQUERADE

maybe i'll try doing it myself ....
