I have been trying to get DNAT to work and I actually have succeeded too, however, not how I thought it would work when reading through the documentation. 1. No matter what I do I cannot get DNAT to work unless I have an entry in eiter the nat or the proxyarp file. Is that really how it''s supposed to be? I can''t find anything about it in the documentation. 2. Also, in the

As the device doesn''t have default gateway, the response to SYN (ie, SYN/ACK) don''t come back to Internet. What I need is a setup to make this connection appears to come from firewall''s internal IP address instead of the public IP of originating requester
