Thank you for your reply Egbert.

For reference, Anders' email is here:

Using the shell command works:
<shellcmd>ifconfig sis1 192.168.1.2/24 alias</shellcmd>

And successfully configured my ADSL modem to use m0n0wall as its default route - all working great!

However I was wondering why setting a <secondary> IP in config.xml was't working, so had a look at the source code of interfaces.inc and it doesn't look like it is possible to do, due to a lack of call to:
interfaces_secondaries_configure('wan');

I guess this is deliberate -  is there a particular reason?


Thanks,
