I Have a strange problem, and I'm not sure how to troubleshoot it.
Mikrotik RB750 <Ethernet cable> Switch - With PCs connected <Ethernet cable> Linksys WRT54GL <Wireless link> Huwei 3G Router
Mikrotik has an IP of 192.168.2.94/24 ,
and a static route 0.0.0.0/0 pointing to Huwei 3G Router at 192.168.2.2
All PCs and the Linksys are in the 192.168.2.0/24 range.
PCs use the Mikrotik as Default Gateway.
This works for about 10sec then stops working.
Mikrotik reports "192.168.2.2 Unreachable" under routes and can no longer ping the Huwei router.
Without restarting anything, I change my PCs gateway address to 192.168.2.2 and the internet works again, but the Mikrotik can still not ping the Huwei router.
Restarting the Mikrotik or Huwei Router makes no difference.
But when restarting the Linksys with the PCs still pointing to the Huwei Router, the route on the Mikrotik becomes reachable again.
This then stays fine again for about 10sec, during which I can ping the Huwei Router from the Mikrotik and then fails again.
Any help will be appreciated.
