Firewall/NAT

Hello,

after upgrading from 1.235 to 1.3 i encounter problems routing LPD from DMZ (192.168.10.10) to LAN (192.168.0.100).
This rule worked in m0n0 1.2XX:
- <rule>
  <type>pass</type>
  <interface>opt1</interface>
  <protocol>tcp</protocol>
- <source>
  <address>comserver</address>
  </source>
- <destination>
  <address>192.168.0.100</address>
  <port>515</port>
  </destination>
  <log />
  <descr>LPD nach Netprint IV</descr>
  </rule>

It looks like the ACK from 192.168.0.100 doesn't get back to the sender.

Please find attached the network traffic under 1.235 which worked and the one without success from 1.3.

Any help is appreciated.
