When configuring your router/firewall you must pick one of the three addresses that are for you use, and set the subnet mask to 255.255.255.248. The gateway is set to the first usable address - the virtual gateway.

==Additional IP blocks==

⚫

If you have additional IP requirements, these will be set up on your control pages and you can change the target address if you need. We will set these up to route to your gateway address initially, assuming (for IPv4) that you are using the last usable address as your firewall/router.

==Dual routers and VRRP==

If you wish to run two routers yourself and use a protocol such as VRRP, set the virtual address as the last usable address. You can use the other two addresses as the real addresses of your two routers. We use VRID 42 for VRRP so use a different VRID if you are using VRRP to avoid any clash.

==DSL or L2TP Fallback==

Line 77:

==BGP==

If you are announcing addresses to us using BGP then the routing and fall-back is managed by BGP. You should set up your BGP routers to peer with the two real router addresses ("A" and "B"). If you have two BGP routers then set up a full mesh (4 peer links). In the event of any maintenance we will cleanly close BGP sessions first causing routing to switch as necessary. You will need a suitable IP assignment and AS number for BGP. We support 32 bit AS numbers.
