Hello list I have a scenario the a computer has 2 PPP connections, where the computer is the ppp client. $ifconfig ppp0 inet 10.0.0.1 p-t-p 192.168.1.1 mask 255.255.255.255 ppp1 inet 10.0.1.1 p-t-p 192.168.1.1 mask 255.255.255.255 for testing purpuses I want packets from ppp0 to ppp1 to actually go over the physical connection e.g. ping 10.0.0.1 -I ppp1 should send the packet over the ppp1 (and out underlyging physical interface eth0) and it should arrive on the ppp0 interface. (routing is taken care of at the ppp server) This proably isn't a netfilter issue(?) but I was hoping that some networking guru would have a solution for me;) route Destionation Gateway Genmask iface 192.168.1.1 * 255.255.255.255 ppp0 192.168.1.1 * 255.255.255.255 ppp1 0.0.0.0 * 0.0.0.0 ppp0 0.0.0.0 * 0.0.0.0 ppp1 regards Mks
