Hi
 
Preparing a server with vmware GSX. On it there will be a number of
virtual machines and I'm using M0n0Wall to act as a firewall. At this
moment however, the server is in my internal network. So the WAN
interface has a private IP:  192.168.0.108 / 24. The LAN interface is
192.168.15.254 / 24. On the side of the LAN interface I have a few
virtual machines (dc01 192.168.15.1 and ex01 192.168.15.2). From both
dc01 and ex01 I can access the m0n0wall webGui. They can also surf the
web, using NAT from M0n0wall and going through my LAN. Their default
gateway is set to m0n0wall (192.168.15.254). On the WAN interface there
is the 192.168.0.0/24 network. Default gateway is 192.168.0.254. My
client pc is 192.168.0.102. 
 
client 192.168.0.102 ---> WAN 192.168.0.108(dhcp) / LAN 192.168.15.254
<-------> EX01 192.168.15.2
 
Now I've created the following rules:
 
Firewall -> NAT -> inbound:   If = WAN, Proto = TCP, Ext.Port Range = 25
(SMTP), NAT IP = 192.168.15.2, Int. Port range = 25 (SMTP), Description
= SMTP incoming
Firewall -> Rules -> LAN:   proto = *, Source = LAN Net, Port = *,
Destination = *, Port = *, Description = Default LAN -> Any
Firewall -> Rules -> WAN: proto = TCP, Source = *, Port = *, Destination
= 192.168.15.2, Port = 25 (SMTP), Description = NAT SMTP incoming.
 
When I try to telnet from my client to 192.168.0.108 port 25, I receive
no reply. 
 
The logfile looks like this:
22:06:47.934316 lnc0 @0:13 b 192.168.0.102,3540 -> 192.168.15.2,25 PR
tcp len 20 48 -S IN 
22:06:41.911158 lnc0 @0:13 b 192.168.0.102,3540 -> 192.168.15.2,25 PR
tcp len 20 48 -S IN 
22:06:38.940851 lnc0 @0:13 b 192.168.0.102,3540 -> 192.168.15.2,25 PR
tcp len 20 48 -S IN 

I tried the same with http. Same result. On the EX01 Webserver I see no
log entry of incoming trafic. To verify that smtp and http work on
192.168.15.2, I accessed them from 192.168.15.1 and this works.
 
I can't figure out what is going wrong.....
 
Any help would be great
Gabrie
