Oh. If you literally "do not have any firewall enabled" or "ipchains
installed", then you do not have NAT (IP Masq) enabled, since it is the
forward chain of the ipchains ruleset that handles NAT. As a result, the
packets from the LAN (probably) go out just fine, but return packets from
off-LAN don't arrive because outside devices (the DSL router itself and the
Internet in general) don't know that your router is their route to
192.168.1.0/24 (they don't know this quite properly; "private address"
*means* unroutable, requiring NAT to work).

To make this setup work, you must install ipchains and, at a bare minimum,
add a rule that MASQs the internal network.

I've deleted the rest of your message because as you describe your setup,
this omission is almost certainly your problem. The easiest solution is to
add one of the drop-in firewall packages that David suggested in the e-mail
he sent last night.
