Here's a rough scheme of my network: -
The network is divided into VLANs. The linksys device is connected to a VLAN20 access port. Clients 4, 3, 2 ping the rest of the network just fine, but Client 1 and DC can ping the linksys ap, but can't ping clients 4, 3, 2. What's wrong?

EDIT: Here's a brief on net config: Router 1 divides the network into VLANs 10, 20, 30, 40, 50 and 111 and has the corresponding addresses in these subnets:,, etc. All the VLANs except the 111 one are routed between each other.
Switches 1 and 2 only have addresses in VLAN10.
The Linksys WRP400 router is connected to a VLAN20 access port. Its static IP address is (mask Tried to apply the but there's no such seeting). Its NAT and DHCP capabilities are disabled so it could act as an access point\switch.
I've noticed that I've also disabled the Dynamic Routing (RIP) feature along with the NAT setting. Turned it on now, but nothing changed. Should I add any static routes?

Looks like a routing or ACL issue - but you need to post more detail for anyone to have much hope solving it. Can you post full IP details along with netmasks, and the router / switch configuration? – James Yale Sep 21 '12 at 9:56
Sure, check out the edit. – khvn Sep 21 '12 at 10:27
I assume that network diagram is much simplified, and you can't just flatten the network into a single subnet? Your subnet mask on the WRP400 router is correct,, all your subnets seem to require this mask. What's the output of "tracert" from one of your wireless clients on VLAN20? – gac Sep 21 '12 at 11:24
Sure, the real network is much more complicated, but I've included everything that matters in the diagram. The tracert output is: 1 1 ms 1 ms 2 ms 2 1 ms 1 ms 2 ms SERVER-X3650 [] ...looks like everything is correct from the client-side. – khvn Sep 21 '12 at 11:33
Looks sensible to me. What's the result the other way around? I'm assuming one hop for, then nothing? – gac Sep 21 '12 at 11:38
