I am trying to replace a netgear router which has a very simple setup with a cisco 1605 router. (I have to reboot the netgear every day)
My setup with netgear (Which works): Cable coming in from Time Warner connects to Time Warners router LAN port from the Time Warner Router connected to WAN port on netgear LAN port on netgear connected to my hub.
IP of netgear router: XX.XX.XX.54 subnet 255.255.255.252 Gateway:xx.xx.xx.53 (This is the cable router) LAN IP of netgear router 192.168.0.1
I bought a 1605 because it has 2 ethernet ports so my plan was have Ethernet0 connect to my LAN and Ethernet1 connect to the Internet.
under config of Ethernet0 I tried to add: ip address xx.xx.xx.54 255.255.255.252 secondary and get the error: ip address xx.xx.xx.54 255.255.255.252 xx.xx.xx.52 overlaps with Ethernet1
If I change the subnet to 255.255.255.254 I get the error: ip address xx.xx.xx.54 255.255.255.254 Bad mask /31 for address xx.xx.xx.54
I only have on static ip address: xx.xx.xx.54, the xx.xx.xx.53 is Time warners cable modem.
Does any one have any ideas of what I should try? The key to me is that it does not like xx.xx.xx.52 which is NOT one of the numbers I typed in. So it must have something to do with the subnet mask. But I don't know what. I took most of this from a working T1 (1601R) and substituted Ethernet1 for Serial0.
Thanks in advance, Rob
