'lo folks,
Anyone know if it is possible to use proxy_arp to proxy network addresses that are derived from RIP updates using gated in Linux? I’ve got the following setup:
Cisco Router #1
eth0: 192.168.4.1/24
ser0: 192.168.3.2/24
Cisco Router #2
ser1: 192.168.3.1/24
eth0: 192.168.2.22/28
Linux Box
eth0: 192.168.2.17/28
wlan0: 192.168.2.220/24
Dlink Wireless (ahem) … “Router”
wireless: 192.168.2.1/24
ethernet: xx.xx.xx.xx (internet)
The Linux box learns the routes for 192.168.3.0/24 and 192.168.4.0/24 through RIP updates from Cisco Router #2. I’ve got proxy_arp and ip forwarding on both eth0 and wlan0 on the Linux box. It proxies fine for the /28 subnet (i.e. I can ping anything on the 192.168.2.0/28 subnet from the 192.168.2.0/24 subnet), but it doesn’t seem to want to proxy for the 192.168.3.0 and 192.168.4.0 networks. Is this possible?
The reason for the overlapping 192.168.2.0 networks is due to the Dlink’s inability to recieve RIP updates or hold a static routing table.
Thanks for any ideas or insight,
