I am having an issue with a network setup. It could be what I am trying to accomplish.
I have a 100mb( fulldp ) connection coming on to my site.
I have the single connection connected from the 100mb circuit going to a un-managed 3com switch.
On the 3com switch I have 2 devices connected. A sonicwall md250 and a linksys router.
Each device is nating IP addresses onto the same subnet.
Sonic wall - x.x.x.178 to x.x.x.283 on a /28 subnet
linksys - x.x.x.290 on the same /28 subnet.
The problem is the firewall is working fine but when I plug in the linksys router it can not get out the internet. I have checked the gateway address and range addresses and everything is fine.
If I put my laptop on the same subnet and give it the static IP of the linksys router it works fine. I have tried multiple routers ( stock linksys and ddwrt ) and same issue.
Funny thing that I noticed is that the first time i hooked the ddwrt router up it worked then on a reboot of the router it stopped communicating with the gateway.
Is it the ARP table getting messed up having 2 routers on the same subnet?
Any help would be great. My next stop was to either put a managed switch in or a router to see what is going on.
