RE: [FW1] NAT on several ports




Hi,


I tried this method but it doesn't work. the firewall accepts the packet and NAT it but no communication can be established.

Regards
Ahmed

Hi there


you only have to define static NAT in your policy editor, something like
this:

Original Packet:
Source: Any
Destination: Valid IP
Service: http

Translated Packet:
Source: Orig
Destination: IP B
Service: Orig

and so on.

Regards

the Public IP is the same and I think that I need to do a static rule and a
route to that server
eg

route add PublicIP mask 255.255.255.255 privateIP

right ???
so How do I put the second one ?

sounds like you just need to add all the services you want to NAT into different NAT rules...

e.g.
	Source		Destination	Service		XlatedSource
XlatedDest	XlatedService
1)	Any		ExternalIP	http		Any
InternalIP	http
2)	InternalIP	Any		http		ExternalIP	Any
http

1 public IP address and several services: dns, www, smtp

address B and smtp to a private IP C
