Mauro, Unless both Aironets have routes to each other (either default or static) they cannot communicate, and AFAIK, the Aironets are layer-2 devices with no routing capabilities. Wireless hosts behind AP1 should be able to communicate with wireless hosts behind AP2 though. Just make sure hosts at both ends have appropriate routes to each other. -----Original Message----- From: lartc-admin@mailman.ds9a.nl [mailto:lartc-admin@mailman.ds9a.nl] On Behalf Of Mauro Cerboni Sent: Wednesday, November 20, 2002 7:32 pm To: lartc@mailman.ds9a.nl Subject: Routing problem Hi everybody, I have 3 routers (Linux boxes with Red Hat 8.0 server), with iproute2 and ip_forward activated; they are linked together in this way: AP1------Router1---------Router2----------Router3---------AP2 AP1 and AP2 are WLAN 802.11b Cisco Aironet 350 access points. I can't ping AP2 from Router1 and Router2 and AP1 from Router3 and Router2. Changing one of the AP with a laptop connected to Router (1 or 3) results in no effects. The routing tables seem correct. Router1 and Router3 can ping each other, so Router2 seems to make right routing. The dotted lines above are 4 different subnets. Any suggestion would be of great help!
