Force10 S60 Layer 3 Inter VLAN routing issue

Hey this is kind of a weird issue but I have a Force10 s60 with the following config and seem to have an issue I have not seen before with l3 switches. My router is on 192.168.1.1 and has a server on 192.168.1.12 that is plugged directly on the router. I have built routes on the router for 10.0.0.0/24 to route to 192.168.1.2 and I cannot get to route from a server on the switch at ip 10.0.0.253 to the server on the router at 192.168.1.12.

All other communication seems normal. I'm able to route to internet from all switch interfaces/vlans and back in. Just seems to be an issue when I try to go from an interface on the switch 10.x network to the 192.x network on router, but keep in mind the 192 network is also configured here on the switch.

I feel maybe there is a loop as I'm getting TTL expired in transit.

The router is configured to send 10.0.0.0/24 to 192.168.1.2, also server on router side is plugged into port 4 if that helps. Server does happen to run many services but yes its only physical one on router side.

Additionally I did find a device running on switch interface 18 on 192.x network that I cannot reach from port 51 on 10.x network.

I made a capture with wireshark if this helps at all

Daniel,

Thank you for all of your help!

I apologize im new to this switch, I have this guide. What is best way to check the logs?

 

Yes it does appear in the ARP table.
