This is situation:
Slackwarebox with 2.4.25 and i use Shorewall to config the firewall.
interfaces ppp0 (eth0 pppoe) ,eth1, dsn0.
The dsn0 is an interface used by dosemu.
dsn0 is in same subnet as eth1, and is attached to eth1 in the dosemu setup.
There is a dos client program that uses dsn0.
lets say dsn0 =192.168.0.15 and the dos program had ip 192.168.0.16 (this is how u must set it up).
In the lan i can connect to and from the dosclient.
But i can't seem to get trough the firewall to the outside (inet) with masq and i can't get packets from the inet forwarded to the client.
Anyone got idea?
