.248 /29 subnet and static IP's

RouterOS Beginner Basics

Hi,
I bought a RB450 and I want it to replace my wrt54g that is routing for my subnet.
It needs to login to pppoe and get a static ip (76.10.188.153)
it should route a /29 subnet (subnet mask: 255.255.255.248) from 76.10.189.153-159

I have read on these forums that these devices are a ‘router out of the box’, but I am having difficulty.

On the wrt54g I have it changed from ‘gateway’ mode to ‘routing’ mode. and RIPv1 and v2 turned on.
aside from that and setting the LAN ip address and entering pppoe info I did not have to do anything special.

I have pppoe client setup and connecting on ether1. it receives the correct IP from my isp.
I have ether2-5 in a bridge and I set the bridge’s IP address to my subnet gateway IP. (76.10.189.153)

I have been reading the wiki and searching for similar setups on the forum but I cannot find what makes the routing work on this device.
Please help!

If you have the routed public IP subnet attached to the RB as well you don’t need the wrt at all except for its switch. Instead of bridging ports I would simply put .189.153 on ether2 and connect it to a cheap switch, and put the servers on the switch. This really should be working out of the box.

Thanks for the reply fewi,

I did get this going after posting this message and before it was approved. I will try to outline what I needed to do.
It was actually as easy if not easier than the wrt54g.

  1. set up the pppoe-client on ether1 (enter username and password and leave the rest default)
  2. create a bridge called bridge1 and add ether2,ether3,ether4,ether5 to it.
  3. set the ip address of the bridge to the first IP in your range of consecutive IP addresses (the subnet’s gateway IP)

I think that was it. It is all working just fine now
Thanks
