Custom nat from lan

aldo

i am trying to add a rule to interfaces.inc as the gui does not support it.
where ever i add it it seems to strip out all my outbound nats

can someone offer a solution of how or where i can put this.

my ruleset is

anchor "smtpredirection"
table <smtpredirection>{ 192.168.50.0/24 }
rdr on {$lanif} proto tcp from <smtpredirection>to any port 25 -> 10.250.3.36
nat on {$lanif} proto tcp from <smtpredirection>to any port 25 -> {$lanif}

my syntax was

/* anchor the outbound nat rules */
$natrules = "# outbound email rules for spam trap\n";
$natrules .= "table <smtpredirection>{ 192.168.50.0/24 }\n";
$natrules .= "rdr on {$lanif} proto tcp from <smtpredirection>to any port 25 -> 10.250.3.36\n";
$natrules .= "nat on {$lanif} proto tcp from <smtpredirection>to any port 25 -> {$lanif}\n";</smtpredirection></smtpredirection></smtpredirection></smtpredirection></smtpredirection></smtpredirection>

You can setup these kind of portforwards from the gui. Set it up as portforward on interface LAN with "external adress" any.

sai

The portforward option is in Firewall: NAT: Port Forward

but what i want to do is this

< 192.168.50.1/32 192.168.50.2/32 192.168.50.128/25 >

and the rest of the clients dont get natted by the smtp rule

That is sourcebased natting which is not supported atm.
