Hi There, Iam using uClinux 2.4.19 as Home Gateway. It has 1 WAN port(Global IP) and 4 LAN ports(Local IP's). When LAN port1 sends a packet to LAN port2, uClinux has to send packet to LAN port2 directly without sending out via WAN port and coming back to LAN port2. Does this support is there in uClinux?. If not where to add the changes needed for this in uClinux?. In linux-2.4.x/net/ipv4/netfilter directory, i find files related to NAT and ip filtering. Any help is appreciated. Regards Ram.D
