Hi, I'm defining some NAT rules for my firewall.My firewall has ext int 'eth0' and internal int 'eth1'. If i want to fwd all SMTP request to internal SMTP server,i define a rule like this.(Kindly see attached file) My doubt is here,in "Original Dist"i have given "Firewall object" itself.But how come this will build rule considering EXTERNAL interface,not internal interface.Bcos in firewall object there is both External and internal interface....How come this will build refering only EXTERNAL interface.. -Thanks -Dilip.M |

It will build two rules using both interfaces. If you only want the rule using external interface, then you should put an object that corresponds to the external interface in the "ODst". This is described in lots of details in the Users Guide, btw. There are also several good examples in the "Firewall Builder Cookbook" on the web site. --vk |
