Using eir F1000 router with Vodafone Fibre

I signed up for eir Fibre (FTTH) last year, after having eir DSL before that. Original modem was a F1000 (rebranded Zyxel) and I had that configured with all the NAT, DCHP settings and firewall rules that I like.
When I upgraded to FTTH they gave me an F2000, but was reluctant to re-configure all the rules again, so kept the F1000, which connected to the Fibre ONT without any further re-configuration.

(I'm only using the F1000 as a router, WiFi duties are off-loaded to some separate access points.)

So, eir jacked the monthly rate up after a year, and so was time to change provider. Vodafone looked like best option, similar 300MB 'unlimited' package for good money. Easy enough switch over given ONT etc is already in place. But, again didn't want to go setting up all the rules and network bits on a new router. So wanted to re-use the trusty old F1000 again.

Turns out, it's easy enough ...

All you need from your Vodafone 'Gigabox' router is the serial number (off the bottom of the router).

From the F1000 Admin console, go to the 'Network Setting' menu, and then choose 'Broadband'. This brings up a list of interfaces on the 'Broadband' tab.
Select the 2nd interface ETHWAN, but click the 2nd last icon on the right hand side for Edit.
Change Encapsulation to PPoE.
This will bring up the PPP information.
Change the PPP Username to "<your-vodafone-gigabox-serial-number>@vfieftth.ie"
PPP Password is 'broadband'
The MTU also needed to be changed from 1500 to 1492.

WAN Configured Edit screen should look something like this:



Save, and it should bring up the connection.



Yes, yes, yes, I know this old Zyxel is going to be the quickest or best. I'm planning on swapping it out for something more dedicated in the long term, but good to get some long term use out of these things, and they are pretty adaptable.
