You even wont have to change the default routes on .15 and .16. 1) Assign 192.168.0.14 for the eth0 interface on the router. 2) Assing 0.0.0.0 for eth1 interface on the router. 3) Add routes .15 and .16 via eth1 4) Add a default gw (via eth0,since we gave only that interface an ip) 5) echo 1 > /proc/sys/net/ipv4/conf/all/proxy_arp P.Krumins _______________________________________________ LARTC mailing list / LARTC@xxxxxxxxxxxxxxx http://mailman.ds9a.nl/mailman/listinfo/lartc HOWTO: http://lartc.org/
