Hi,
I implement that and it's working or I hope so. Create a group, name it (i.e.)LOCAL+TR, with the local-net Network Object + all the translated valid ip add's (I created a false Workstation with the translated address as internal for each translated IP). At the external IF, you mark other addresses and in the internal IF you select specific and the object will be LOCAL+TR.
In my opinion this may work, Any other ideas ?
Regards, A.Lopez

COM Asunto: Firewall-1, Static Address Translation problem [2] Fecha: sábado 2 de agosto de 1997 15:31
Thanks to everyone who answered.
The problem was (and still is) the anti-spoofing feature. The manual says you should add the hidden and the official ip addresses to both the internal and external interface on the firewall. This doesn't help, the firewall still drops the packets. But as soon i as remove the antispoofing features (ie. setting both interfaces to accept any ip's), everything works just fine.
Since i really would like to use the anti-spoofing features, this is a bit of a problem. Any ideas?

com Subject: Firewall-1, Static Address Translation problem
Hi!
I have a problem with static address translation. When the client on the inside connects to the outside, everything works fine. But when a machine on the outside tries to connect to the client's valid ip, it just won't go trough the firewall.
I have configured the Network Object, Workstation, Address Translation for Automatic Rules, Static and the Valid IP adress.
The logs on the Firewall-1 says that the packet is accepted, but it won't reach the internal client.
It can't be a routing problem, since it works fine when the client connects to the outside world. The source IP after the translation is also correct.
