Your configuration of the two nics on router2 is wrong. My guess is that you have a routed subnet supplied by your ISP and that you have taken the first usable one (xx.xx.58.129) and used it on the LAN i/f of your (ADSL?) modem. Router 2 now gets .130 on its rl0 and that's fine but you have applied .140 to rl1 and both interfaces are in the same network: xx.xx.58.128/28. You cannot do that and expect routing to work in r2. 2 ways (maybe more possible but I don't have all day 8-) ) to get around it. 1> alias ALL of your IPs except .129 onto rl0 and then use RFC1918 addrs on rl1 and its attached hosts. You can then rdr or binat them to the correct addresses on rl0. 2> You can use a pair of RFC1918 IPs on the modem and rl0, static route the /28 to rl0, configure rl1 to use .129 and hang all (up to 13) hosts on a LAN there. Case 2 requires tricky NATting and pf rules but I have done it several times and it just works but your original post makes me think you'd need a few more clues first. So go with #1 for an easier life. Any replies/questions on list please. Offlist replies >/dev/null Rod/ >From the land "down under": Australia. Do we look <umop apisdn> from up over?
