[afnog] Router Interface not responding

[Alamicha Chapuma]

Dear All,

We have a router with 2 ethernet Interfaces.  One is connected to a LAN of
real ips 62.x.x.x and the other to a wireless network with private ips
172.x.x.x

All has been working fine until recently where we are failing to ping the
wireless interface of the router from the LAN side of it. Also some of the
wireless devices on the wireless side of this router could not be pinged.
The only thing that happened is we reconfigured a wireless access point to
work in router mode.  This wireless access point can be reached from the
62.x.x.x LAN. Further the router can be pinged from the wireless side (i.e.
a host on the wireless network with ip 172.x.x.x can ping the router's
172.x.x.x address).

How do we resolve this problem?  A traceroute from our 62.x.x.x network gets
up to the router and stalls/timesout on the router.  However, if we ping the
172.x.x.x  interface from the router itself there is no problem.

For information purposes the router is set as the main gateway on the
wireless network.

What to do????
