OK, this was my response (originally sent via email, not to the list). This will only work for 2 RA4000s... ----------begin included message---------- >I got 5 and a cisco router. OK, This won't work for you then, but I'll tell you what I did with 2 RA4000s and maybe it will give you some ideas... My situation is this, we're a small ISP, with 2 RA4000s(72 ports each). Well, we've got a class C for dynamic dialup and a class C for static dialup. If you use the same class C for dynamic, static addresses (on one RA400) and the IP address for the RA4000 itself, then there's no problem. The problem is when you have more than one RA4000 and have the dialup IPs on a different class C as the RA4000. What I did is this: Used class C number 1 for the dynamic dialups. Used class C number 2 for the static dialups. Selected IP addresses from class C number 2 for each RA4000 and the cisco. Since the RA4000 is using the same class C as the static dialups, the RA4000s will "proxy-arp" for the static addresses...but then there's the problem that class C number 1 addresses won't "work"...so, on the cisco: ip route X.X.X.0 255.255.255.128 Y.Y.Y.1 ip route X.X.X.128 255.255.255.128 Y.Y.Y.2 ip subnet-zero XXX.XXX.XXX = Class C number 1 YYY.YYY.YYY = Class C number 2 (.1 = 1st RA4000, .2 = 2nd RA4000) use (X.X.X.[1-127]) for RA4000 number 1, and (X.X.X.[129-254] for RA4000 number 2... ---------- end included message ---------- Hope that helps...
