Not passing traffic

[FrothingdogMember]

I’ve been trying to get Zeroshell working on our Wireless Network.

We currently have Soekris Boxes running OpenBSD routers at all our Tower locations which works great.

I’ve been having trouble getting Zeroshell to work. Bascially the setup looks like this:

TOWER B
ETH0 (Private and Public for Backhaul to Tower A)
inet 10.1.34.2 netmask broadcast 10.1.34.255
inet 68.x.x.x netmask broadcast 68.x.x.x

ETH1 (Private and Public for AP and 3 Backhauls and DHCP Pool
inet 10.1.4.1 netmask broadcast 10.1.4.255
inet 69.x.x.109 netmask broadcast 69.x.x.111
inet 69.x.x.129 netmask broadcast 69.x.x.131
inet 69.x.x.225 netmask broadcast 69.x.x.255
inet 69.x.58.225 netmask broadcast 69.x.58.227

TOWER C
ETH0 – (Private and Public for BACKHAUL to TOWER B)
inet 10.1.4.4 netmask broadcast 10.1.4.255
inet 69.x.58.226 netmask broadcast 69.x.58.227

ETH1 – (Private and Public DHCP for AP)
inet 10.1.39.1 netmask broadcast 10.1.39.255
inet 70.x.x.129 netmask broadcast 70.x.x.135

The DHCP side is working ok…I just can’t pass traffic out ETH0 from the DHCP on ETH1.

I set the GATEWAY on Zeroshell for the other end of the /30 on Tower B ( like we always do) but I still can not pass traffic. If I give my laptop the half of the /30 that is supposed to go on the Zeroshell box and hook into the Backhaul directly it works fine.

So I’m thinking that there is something funky going on with the gateway in the ZEROSHELL box that I’ve missed.

Any advise or suggestions?

A network diagram could be better than many words.

I’ll see what I can do

Here’s a rough layout:

BTW the Public IP’s have changed for security

I think there is a problem in the routing tables. Does your OpenBSD box support RIPv2? In this case you could enable RIP on both the boxes and automatically get a valid routing.

The Routing works fine. If I give my laptop the /30 address that is assigned to Zeroshell it works fine. It’s just once I plug into the Zeroshell box I can’t get it to communicate with TOWER B’s side of the /30.

Please use the [Utilities][IP Check] and post the results of the arp check, ping and tracepath. Try either the IP of the gateway or an external IP.
