[Shorewall-users] DNAT and Port Reroute on same interface

[Eric Kaufmann]

Hello,

I am trying to forward port 27001 to 27008 on the same interface. I have
tried to the following.

DNAT net loc:27001 tcp 27008


I did put the ip of the address of the machine after loc:. But that didn't
work.


Also tried the following. But, also didn't work.


DNAT net fw:27001 tcp 27008


These are the zones I have defined.


#ZONE TYPE OPTIONS IN OUT

# OPTIONS OPTIONS

net ipv4

nat ipv4

fw firewall

These are the interfaces I have defined.

nat eth0 detect dhcp

net eth1 detect dhcp

nat ib0 detect dhcp

Thanks,

Eric

You have the port numbers reversed in that rule. It is redirecting port
27008 to local port 27001.
