And I can use the internet from the computer on gi3 (vlan4)
The internet from 192.168.4.x works fine
And I can ping the server 172.16.0.6 on vlan1 from gi3
I am able to ping from 192.168.4.x to the server
But if I try to ping the router from gi3 (vlan4), I can see (on mirrored port with wireshark) on gi1 all 4 ping requests and all 4 replies. But on gi3 I get no replies. I see only the 4 requests.
I ping from 192.168.4.x to the router LAN interface IP 172.16.x.x I see the request but I do not receive a reply
The server is considered directly connected and does not make a routing decision, therefore the packet destination will go to the server and come back as the route is through the switch only. When trying to ping the router from 192.168.4.x to 172.16.x.x, the router does not know the path back to forward the packet to the 192.168.4.x network. Your static route may be adjusted to be something such as 192.168.4.0 /24 172.16.x.x <- IP of the VLAn1 interface. Now, keep in mind, if your default gateway is the router's LAN ip address, you won't ping the router. But, if the computer's gateway is the switch's vlan interface, it should be able to get a reply from the router LAN side.
