you may want to double check that: /proc/sys/net/ipv4/ip_forward is set to 1
you can either add an echo "1" > blah to your iptables script or you can set ip_forward=yes in /etc/network/options -----Original Message----- From: Jeremiah Savage <[EMAIL PROTECTED]> Sent: Fri, 29 Jun 2001 21:31:44 -0700 (PDT) To: [email protected] Subject: simple router Hello, I know this is a firewall list, but I figure routers are close cousins, and this router will eventually run some iptables rules, so here it goes... I am attempting to construct a (simple?) router based on Linux 2.4 with iproute2. I have 3 ethernet cards on the router, with eth0 connected to a host,eth1 connected to a server and eth2 connected to another computer. xx.yy.88.101 +--------+ | | | host | +---+----+ | xx.yy.zz.aa | | |eth0 - xx.yy.88.100 | | +---------+ | +----------------+ |another | eth2 | | |computer +---------+ router | | | | | +---------+ +-------+--------+ xx.yy.zz.ab | | eth1 - xx.zz.110.145 | +---+-----+ | | | server |xx.zz.110.148 | | +---------+ I am simply trying to get traffic through eth0 to eth1 so it can get to the server and get back out, but so far I can't ping the server through the router, although the router itself is capable of pinging the server (so the link eth1 is active). And I've verified that eth0 is also active as the router and the host can ping each other. So how do I get the router to pass traffic through to the server? I've tried # ip route add to unicast xx.zz.110.148 dev eth1 RTNETLINK answers: File exists and yet the host still can't ping the server. And I've tried making eth0 "promiscuous" # ifconfig eth0 promisc but that doesn't help either. Anyone know the magic incantation that I need? -- Jeremiah __________________________________________________ Do You Yahoo!? Get personalized email addresses from Yahoo!
