ProSafe XS508M losing connectivity between laptop and router after rebooting router
Hi there, I have a switch ProSafe XS508M and my router and ubuntu server are connected through it. The network interface configuration of the server has two IP address: LAN and WAN ip address...
Thanks for your comments schumaku . We have this:
- server interface: IP WAN (172.23.8.141) and IP LAN (192.168.1.4) to swicth both in the same physical interface
- switch to router (and the router IP is 192.168.1.1)
- The server has two other interfaces, each of them goes to a different switch with a different network IP,so these are independent of the router and Netgear switch.
- The router does NAT so this is why we have the WAN+LAN connection to the server.
- The switch has has two more devices connected in the same LAN IP network (192.168.1.X) as the router (and Netgear switch)
Then the issue is: if we reboot the router, we loose connectivity between the server (192.168.1.4) and the router (192.168.1.1) and the only way we found to fix this was rebooting (power cycling) the Netgear switch.
Do you know how we could debug/troubleshoot this? Or maybe any of the the points of the list are incorrect?
Thanks a lot!!
Ok, I don't like to promote such a design with two different security zones on the same network, without any seggregation.

This reads like a "simple" L2+ issue where eg. the ARP resolution does not work for whatever reason. Hard to imagine the switch would block anything in this part of the networking business.
