 Subject:  Accessing ADSL Router box on WAN side of m0n0wall

Hi all,

Just upgraded to m0n0 1.2, and it's just as great as I'd hoped. Thanks!

I'm using m0n0wall to protect my home network ( from the
internet. I'm connected to the internet by an ADSL router (D-Link 
DSL300-T) running in bridge mode, then doing the PPP authentication from 
m0n0wall as PPPoE. This is (or has been) utterly, utterly reliable.

The one thing I want to do is to get access to the router's (sucky) web 
interface from inside my LAN. My router's configured as, 
but it's obviously on the WAN side of the firewall. You can still access 
it while it's in bridge mode, but because it's on the "wrong" side of 
the firewall, ARP requests don't make it across; it's a private network 
connected to the public interface.... you get the idea.

I thought I might be able to do Nasty Stuff with the Proxy Arp, but it 
doesn't appear to do what I mean. Am I using the wrong tool? Is this 
even possible? (I can shift the DSL's IP address if it makes things easier).

Hopefully unnecessary network diagram:

--------------+       +------+        +-------------+   |      L| m0n0 |W       ||
/24  (LAN)    +-------+ .3.1 +--------+ADSL Router  +---Internet
--------------+       +------+        +-------------+

Apologies if this is a FAQ, but I have looked.

thanks in advance.
