Dual WAN microwave issue

[nerdifiedgeek]

I've been trying to figure out a networking issue with a client of mine. I'll try to be as detailed as I can about everything.

The information we were given is this..

Point to IP: 192.168.167.129

Out IP : 192.168.167.130

Subnet Mask: 255.255.248.0

Their Router IP: 192.169.29.0

The connection is coming into the building via a microwave and through a fiber optic line, through a converter to ethernet and they have it setup to plug into a Cisco 1841 router that appears to have an IP address of 167.26.10.200 according to the label the stuck on the router (I've tried bypassing this router and just plugging directly into the main router because I don't understand the purpose of it).

Next it is connected into a RV082 Cisco router. This is a dual WAN router with the ISP plugged into WAN 1 and this other connection is connected into the WAN 2.

In the router settings I have tried to set a static IP address, but the input I have to fill in is this..

WAN IP Address
Subnet Mask
Default Gateway
DNS Server

I do not have a DNS server given to me, but I was told I could try using the DNS server for our ISP for this. I've tried every combination I can think of, and nothing works. I have tried pinging their router, and the point to address and get either a request timed out or that it is unreachable. I've tried automatically detecting settings as well instead of setting a static IP and still nothing. Typically this is my manual settings I've been trying..

WAN IP Address: 192.168.167.130
Subnet Mask: 255.255.248.0
Default Gateway: 192.168.29.0 (I've tried 192.168.167.129 as well)
DNS Server:(road runner DNS)

I was told that the subnet mask for our LAN needed to be the same as the WAN (which I don't know is true because the ISP subnet on WAN 1, which is road runner, has a different subnet than our LAN and works fine), but if it helps our LAN is setup to the standard 192.168.1.1 with a subnet of 255.255.255.0. I have not been able to change the subnet, it only gives me a drop down menu to choose from with a list of subnets but I can't put one in to match the WAN I'm trying to connect to. Again, I doubt that is important, but just in case it is. I have tried changing our router LAN IP to 192.168.167.130, but I that didn't work either.

I know very little about networks, but I've tried everything I know to try. If it helps, this WAN is to connect a program on their computers to another sytems. I have to go to the command prompt and "route add" the IP address for the software to use it. Since I can't even ping the IP though I know things aren't being configured right. I've also tried plugging the ethernet cable into my laptop without going into any routers and manually setting the IP address to 192.168.167.130 (our assigned IP) and the subnet mask of 255.255.248.0. With those manual settings, I still cannot ping anything.

From your laptop are you able to access any other hosts? I ask because it is a common practice to disable ICMP messages. (Ping is an ICMP message.)
Try pinging a known responder and check the response.

ping www.dslreports.com

If an error is issued about being unable to resolve the name, there is a DNS issue. Ping using the IP.

ping 209.123.109.175

If this fails, there is a communications issue.

The microwave I am connecting into does not have access to the internet. So connecting my laptop directly through the microwave would not give me any ping returns. While I was connected to the dual WAN router I was getting pings from IPs on the ISP though through the other WAN.

Then run a trace route to the host on the end of the microwave link.
In Windows the command is tracert followed by either a FQDN or an IP address.
Examples:tracert www.dslreports.com

tracert 209.123.109.175

*EDIT* It seems to me that the network setup is missing routes to send traffic to the proper WAN port.
This should be automatic. Perhaps the disconnected box had custom routing tables.

I ran a tracert last time I was there. I've never used it before so I didn't really know what to look for, all I know was it failed. I can go back and copy over the results I get if you want me to.

I'm guessing the added 1841 router had the routing table in it you're thinking? It's certainly possible, but I have tried everything I can think of both with it connected and with it not connected, doesn't seem to make any difference either way.

[ua549]

The trace will show each hop by IP and/or FQDN. From your description of the network setup there should be 3 hops or more - device, router, router, device. If the trace fails on the first hop, there is an issue in the device. If the trace fails before it hits the remote router there is an issue with routing on your end. If the trace fails after hitting the remote router the issue is on the remote end.

I tried the tracert on all the IP addresses given and they all showed failed routes that tried to find it's route through the internet, which it's not suppose to. It's suppose to be going through the router with the 167.26.10.200 IP address that is connected to the WAN2 port. I couldn't even get a ping or tracert on that IP.

One food for thought. From the Cisco 1841 router, is it suppose to have a crossover cable to connect into the main router's WAN port? Right now it's running a straight through cable.

At this point I suggest that you map each connection with its device cable type, IP info (ip, mask, gw, dns, routing tables) so that you have a visual of how the network operates. Make sure to include client nodes.

There seems to be a significant error in the layout and/or configuration. Seeing the all encompassing view will help you identify any errors.
