Firewall/NAT

After i upgraded my m0n0wall from version 1.22->1.23->1.231 my Tuxie couldn't communicate with
syncing sites either ftp download sites. My m0n0wall doesn't let it to pass. Though, i've made sufficient
port forwardings. How it is possible that m0n0wall suddenly denies activity within DMZ?

There's a topology:

[TUX(192.168.1.253)]---[Zyxel GS-2024(192.168.0.60)(Vlan2: DMZ)]----[m0n0wall(192.168.1.1)]-------[WAN]
                                                          |
                                                          |
                                           [compies inside lan]

Does other connectivity out to the internet work?  Or is all traffic from the DMZ blocked?

There's also windows based fileserver in DMZ zone and from the beginning it's connection has worked
properly.  DMZ feature is working partially.

PROBLEM SOLVED!!

(There was a false setup in firewall dmz rules section. Original didn't allow "any"-protocol connect to WAN.
TCP/UDP was originally selected.)
