I haven't had a chance to try the 2830 directly yet but making it the DMZ host made no difference sadly :cry:

I needed to do this for a company issued Watchguard behind my 2925 at home.

On the 2860, either via telnet or using the web console window, issue the command:

Code:
srv nat ipsecpass on

The 2830 still needs to be set as a DMZ host in the 2860 though.

Edit: Oh, and make sure "Enable IPSec VPN Service" and "Enable L2TP VPN Service" are disabled under "VPN and Remote Access >> Remote Access Control Setup" in the 2860 too.

Thanks for the suggestion. I gave it a go but still nothing :cry:

Is it possible to temporarily connect the 2830 directly to the internet and prove you can establish your L2TP/IPSec connection to it.? (Just to eliminate configuration (or compatibility) problems on the 2830)

or

Perhaps configuring the 2830 as the "DMZ Host" on the 2860 would do the trick?

Unfortunately I can not test this directly with the 2830 as its not a VDSL modem.

Any old (ISP-supplied) VDSL-router in Bridge Mode could be used to temporarily connect the 2830 to the Internet...if you have one to hand.
