Strange Routing

Hi Guys,
I have a strange one or at least I think it is strange. I have an 433ah acting as an AP which is fed by a Nano bridge ether1 the side facing the nano bridge has an address 10.6/24 and the AP side has a range 55.0/24 the AP has 55.1 as its address. I have static routed down to the 433 and can access it fine over 10.6 or 55.1 I have a few clients hanging off the AP using Ubiquity Nanao's I can access the client at 55.2 but not the client at 55.6
Here is my routing table
0 A S 0.0.0.0/0 10.10.10.5 1
1 ADC 10.10.10.0/24 10.10.10.6 ether1 0
2 ADC 192.168.55.0/24 192.168.55.1 wlan1 0
when I tracert from my computer the hop I get response from is 10.10.10.6.
I set up a pptp server on the 433 and can gain full access to all the clients that way.

I find this most strange as I can get to 55.2 and all units are set up the sameway

You can torch the AP's WLAN interface and make sure that the traffic is heading *to* 55.6. If it isn't then perhaps you can't get ARP resolution for 55.6. If the outbound traffic is fine look at the 55.6 client and check its routing table against another 55.x device which does not show the same symptoms.

The routing entries you showed are presumably for the AP device but the routing entries at the clients and at your originating device also play a role in the round trip path so you could upload those if no resolution.
