[suse-security] SuSEfirewall 2 - redirect ports on internal interface to DMZ
From: Dirk Enrique Seiffert (dscaribenet.com)

I am moving a Mailserver from the internal network to the DMZ. This move
should be invisible for the enduser. Lat but not least: Some hundred mail
clients are configured to consult an IP, not a name: I can't solve the
issue by configuring my DNS server.
This is my configuration:
200.x.x.x (public IP)
I have to access the mailserver by an IP in the 192.168.0.0/24 range.
External traffic I can easily redirect with FW_FORWARD_MASQ= to an IP in
the DMZ. Internal traffic I can redirect to a local port on the firewall
Is it possible to redirect all traffic coming on the internal interface
for 192.168.0.249 to 192.168.254.2 ?
Any Custom rule? I was googling quite a while to, didn't find any rule
doing a forward on the internal interface.
Any idea is appreciated!
