Charles: I have cleaned few lines to reduce the clutter. ------
ARC1(Port 15) 12.21.237.241 IP Pool: 12.21.237.48/C ARC2(Port 16) 12.21.237.242 IP Pool: 12.21.237.96/C
That's going to give you overlapping pools, which will cause big problems. If there was more info about your network (is it subnetted, are you doing this all off of one /24, etc.??) it would be much easier to troubleshoot. ANSWER: We have the entire IP block 12.21.237.0/24. I have mapped the IP addresses for servers, IP addresses, etc. I can change the mask, if it will help or change the size of the ip-pool for each pool to just 24. This does not seems to be the problem. ------ Unless you were using it before, turn RIP off, that's just adding more complication to an already hazy problem. ANSWER: I have not changed RIP. It was already ENABLED. I am told that it would not hurt to leave it ENABLED. AT&T ENABLED RIP on CISCO router and it did not resolve the problem. ------ "sh ip route" should do it, you don't need enable privs for that. ANSWER: No idea what you are asking me to do. I did use the above command & it displayed the ROUTING settings ------ If indeed you're using one /24 for everything and have a totally "flat" network, you're going to have to make sure the ARC is proxy-arping for your dialup users since they are getting assigned out of your main LAN block. We just dumped the last of our dialup gear, so I can't poke around, but here's two things someone can probably clarify for you: -how to explicitly set a range of dynamic IPs. You MUST make sure you have nothing else on the LAN using those IPs. You MUST make sure that you are not using IPs from the same range on both ARCs. If you fail to do that, you will have a problem much like what you described. -how to ensure that the arc will proxy-arp for the dialup connections. Do those two things, then see how your problem goes. Again, do a traceroute from outside if you see it happen again AFTER making sure you've got the above two issues sorted out. ANSWER: - as I mentioned earlier, I have a map of IP addresses. I do not believe that IP addresses are being assigned to more than once. I will change the MASK on the IP pool for the ARC & see if the problem goes away. - I will look into proxy-arp. Never done it but I will figure out unless somebody has a better suggestion. ------ Charles thanks again. These responses keep me going. Kirti
