Here is network schema:
192.168.2.200 - Switch layer 2 ---| |--X0 LAN 192.168.2.254 |---Switch layer 3 ---| 10.50.40.40 --- Swtich layer 2 ---| |--X6 LAN 10.50.60.1 |-- WAN
The layer-3 switch has multiple IP addresses: 10.50.40.1, 10.50.60.6, and 192.168.2.1.
The default route for the layer-3 switch is 0.0.0.0 for gateway 192.168.2.254.
There are three VLANs on the the layer-3 switch, and routing is enabled.
VLAN1 (192.168.2) is the default VLAN. There were 3 switches. I changed those switches to make VLANs, change network addressing, and delete all 192.168.2 addresses.
There are other VLANs, but for clarity I show only one.
I've got these issues:
- When machine 192.168.2.200 has 192.168.2.254 for its gateway, it can get to the Internet and ping 10.50.60, but it can't ping 10.50.40.*.
- Machines in 10.50.40.* have the gateway 10.50.40.1, can't get to the Internet, can't ping 192.168.2.254, can ping all other 192.168.2, but they can't make MSTSC or access network shares or nslookup the DNS (all services can't go).
So, I've made these changes:
On the SonicWALL, I've added a route to access 10.50.40 with gateway 10.50.60.6.
Now, from 192.168.2.200, I can ping 10.50.40 and 10.50.60, but from 192.168.2 and from 10.50.40, I can't MSTSC or network share or whatever.
On machine 192.168.1.200, I set the gateway to 192.168.2.1
Now, all over network services are reachable for all networks. I can MSTSC and network share etc., but now from 192.168.2.200, I can't ping 10.50.60.1 (X6 interface)!
From machine 10.50.40, I still can't ping 192.168.2.254, and I can't get to the Internet.
- If I'm on VLAN1 (default vlan 192.168.2), I can't ping the X6 interface.
- If I'm on VLAN4 (10.50.40), I can't ping the X0 interface, and VLAN4 can't get to the Internet.
I don't know what's happening. Please help if you have any ideas.
I've changed the default route on the layer-3 switch to the gateway 10.50.60.1, and now 10.50.40 can get to the Internet, but 192.168.2 can't.
It seems to be a SonicWALL issue.
