What is the exact error message you receive when you try? Are you trying
to use hostnames, or IP addresses?

Looks OK

Routing and forwarding OK on ALGS-03

Routing, and forwarding, probably OK on GATEKEEPER, masquerading (or NAT)
probably OK for 192.168.0.0 - unknown about 192.168.1.0.

On ALGS-03, run tcpdump and watch the packets on BOTH interfaces. Who is
having the problem?

On your followup to Unruh <unruh-spam@xxxxxxxxxxxxxx>, in article

So look at the packets on the wlan0 interface on ALGS-03. Are the packets
being sent to GATEKEEPER? Is GATEKEEPER responding?

Another thing to look at - what firewall rules are in place on GATEKEEPER,
ALGS-03, and ALGW-05.
