We are running fw-1 4.01 on a nokia IP330 an got some strange problems.
First of all our configuration

Ethernet A, xxx.xxx.xxx.3 : WAN only IP address is our router xxx.xxx.xxx.1
Ethernet B, xxx.xxx.xxx.1: LAN , RFC-Hosts, NAT whole segment to one IP
address xxx.xxx.xxx.5
Ethernet C, xxx.xxx.xxx.3 : DMZ, RFC-Hosts, NAT dynamically each RFC-Host to
corresponding official IP address

When connecting to our mailserver within the dmz (regardless if from lan or
wan) everything seems working fine. But every 5 minutes we get a no route to
host error and it seems like the firewall starts sending the packets back to
the router instead of passing them to the dmz.

Is it possible that this error occurs because we got the fw-1 interface
installed with a higher IP than the mail-host (fw-1 is xxx.xxx.xxx.3 und
mail-host is xxx.xxx.xxx.2) ?
Somebody knows what going on ?

regards
Sven
