If you have dgteam firmware then modem only is a selectable option. If you use the official firmware then it's hidden (http://vpncasestudy.com/download/DG/DG834_Tips100.pdf) - this is not rocket science.

The best way to handle ips is separate them i.e keep the modem on 192.168.0.1/255.255.255.0 and router on 192.168.1.1/255.255.255.0 which should work on any recent router (Asus use a modified tomato code for their firmware which is why it "just works" for you andy ;) however your MTU should be 1500).

As for the op connect the dg to your laptop/pc, get that dg into modem mode, double check the lan ip is 192.168.0.1/wifi is off and plug it back into the phone socket.
Now connect lan port 1 on the dg to the wan port on the tp.
Connect your laptop to your router and set it up i.e. put it's ip back to 192.168.1., enable dhcp, sort your dns so it isn't pointing at the router but an actual dns server and enter your isp details under the wan option.

It should then just be a case of restarting the modem, router and renewing the lease of your devices (I've sometimes found restarting windows the only way to get things working).

Why keep them seperate? All it is is a management interface. Ethernet is layer 2 so is irrelevant to IP addressing...

I noticed it was different on the router compared to my Mac (which shows 1500 in system prefs). However when I checked Zen's tech help (my ISP) it says the default for them is 1458.

This is common, as when it's encapsulated by PPPoA it adds a header to it IIRC

Done as per this post and i no longer have an internet connection. Setting the dg834 to modem only mode seems to kill it stone dead. The tp link just sits there with the WAN status saying connecting. The dg seems to negotiate the line as the i light blinks orange for a few seconds before turning green.

The tplink wan is set to pppoe with the isp username and password set. Secondary connection is disabled, mtu is 1480 by default (i've also tried 1458 which was the dg default), service name & ac name are blank, use specified ip is off, detect online interval is 0 and no specific dns servers are set.

If i go back to running it via dynamic ip with both routers enabled (which works perfectly as far as i can see), what should i turn off on the dg? (Nat, upnp etc)

Using that method you are double natting, which really isn't recommended. You may find headache in maintaining sessions with games etc.

Why can't you use the TP Link alone?
 
Can't get an internet connection with the dg834 in modem only mode as the tp link is unable to connect via pppoe even though the settings i've put in are correct. It doesn't give me any failure messages or errors it just stays at connecting.

Old habit from times when tomato didn't like them being the same (also convenience) ;) Still, I haven't had issues with any linux based routers in the past few years since they sort themselves out when you enter any modem ip. If the op has issues he should just stick modem on 192.168.1.1 and the router on 192.168.1.2 (or whatever).

As for the op - when in modem mode the dg just acts like any off the shelf adsl2+ modem. The only thing you need to log in to it to do is change its ip. The cable router should be running everything but three quarters of the battle is usually getting the router to talk to the modem. You can find pages and pages on google of people with exactly the same issue as yourself.

If you're in the fortunate position of having a static ip then dgs just seem to work. Have you tried simply selecting dynamic on the tp? The really should be all you need.
