Hi
I have a need to configure NAT on a Juniper netscreen 500 firewall running OS 5.4.0r21.0 (Firewall+VPN). Old I know, but I cannot do anything about this for now.
I am unfamiliar with NAT on a netscreen, but it looks like I can do policy based NAT using the egress IP address.
However the issue I have is that connectivity is over an IP SEC VPN to an external customer site and I need to NAT a private 10.xx.yy.zz IP address on a local server to a differnet IP address/egress IP address as the customer uses the same 10.xx.yy.zz IP range on their side and so they cannot route from my 10.xx.yy.zz IP address to the nodes at their side or from the nodes at their side to the 10.xx.yy.zz IP address of my server.
So I need to be able to NAT traffic initiated from my side to a differnt IP address/Egress IP address and send it to the customer side. But I would also need to be able to handle traffic initiated FROM the customer side towards whatever NAT IP address my server uses.
This is pretty urgent, so any assistance provided would be very much appreciated.
Cheers
