hi

i have a question about routing and nat

i have 2 internet on wlan1 and wlan2
ether1 connected to local1
ether2 connected to local2

how can i nat wlan1 to ether1 and wlan2 to ether2?

thanks

add nat rules with specified in and out interfaces.

thanks for your answer

when add the nat rule :

ip firewall nat add chain=src-nat action=masquerade in-interface=ether1 out-interface=wlan1 disable=no

OS type this error :

failure: ingoing interface matching not possible in output and postrouting chains

my config is problem?

sorry forgot that.
Then there are two options

  1. use source address or source address lists instead of in interface
  2. or use mangle to mark connections in forward with specific in interface and then use that connection mark in nat rule.

i have a problem with no.1

when one gateway is enable and use that range of dst-address everything is ok
but when two gateway is enable,two gateway synchronic not lable “AS” ,one of gateway is black and one of gateway is blue

when one of gateway is blue,this gateway not work and your no.1 is not working

Then use mangle to mark connections as in 2) option in my previous post.
*) Then mark routing based on those connection marks.
*) add gateways with routing marks
*) add nat rules with specified out interface

now both gateways will be active.
