I've just picked up a used vigor 130 so that I can utilise my (being delivered) unifi USG as the fritzbox doesn't do bridge mode.

I've got the DV130 setup as 192.168.0.1 with DHCP off and my fritzbox is running on 192.168.1.1 (also with DHCP off); I've got a whole bunch of static IPs assigned to various things including my domain controllers so shifting things up by 1 is a no go and I don't actually need to see the vigor on the lan in general - makes it neater for fibre install later too.

What I have done so far is:

Assign a static route on the DV130 to 192.168.1.0 with netmask of 255.255.255.0 and a default gateway of 192.168.0.1
Assign a static route on the 7390 to 192.168.0.0. with netmask of 255.255.255.0 and a default gateway of 192.168.1.1

I figured this would be sufficient to be able to route clients from my LAN to the DV130 but it doesn't want to work.

Is someone able to point out where I am going wrong? I've never played with subnets before but its always a good time to learn right?!?! Be good to get this sorted before my USG arrives so I can just plug and play!

Thanks,

Chris

Just a FYI, the fritz can bridge, it's just a bit of a hack to activate it.

If you don't setup any INet interface, it bridges automatically...

static routes look right at a skim.

The DV130 will only be performing NAT for 192.168.0.x so devices on 192.168.1.x won't have Internet access.

Just set the DV130 LAN range be on 192.168.1.x and you can use static routes to forward traffic from the Fritzbox to the DV130 on the same subnet. If that doesn't work you could just use a double NAT setup temporarily.

I think OP needs to clarify what type of broadband connection (ADSL / VDSL) they are on.

If they bought the DV130 to bridge the WAN connection to LAN then you shouldn't need to set up any static routing.

Just set up the DV130 in PPPoA to PPPoE passthrough (for ADSL) or bridge mode (for VDSL). Instructions here. At most you will need to reconfigure the WAN interface of the Frizbox. e.g. ADSL/VDSL would be untagged PPPoE on the Ethernet WAN port (passthrough or bridged from the DV130).

The DV130 would be redundant for UFB/fibre.
