I have a Mikrotik Port 1 connected to the Internet Modem and port 3 connected to the internal switch… the Mikrotik has internal IP of 192.168.128.1 and I have devices set with static IPs on that subnet… so far so good the Mikrotik can see all the devices, and vice versa…
Now on the network there is also a Sonicwall… and it uses 192.168.1.1 as its gateway address for the other devices on that subnet… now my problem is I need the Mikrotik to be able to see into that subnet also… I’ve never done this so I’m stumped right now…
If anyone can point me in the right direction it would be greatly appreciated
Your term “see” is a bit vague. Do you want traffic to go from the Mikrotik to the sonic wall or must they just ping each other. Plug another port from the Mikrotik (port4 for EG) into the switch that your sonic wall is connected to. Then assign port 4 and up in the 192.168.1.0/24 subnet and they will “see” each other. However I don’t know why you would want that
Drawing a diagram of your network would be useful.
DO you mean MT is connected to modem on wan side and then is connected to a managed switch and also connected to the managed switch is a SONICWALL device also acting as a router?
If that is the case, I believe all the changes are required on the sonicwall but not 100% sure.
It’s hard to be sure of your topology from your description, however…
It sounds like you would benefit from knowing that you can assign multiple IP addresses on different subnets to the same interface on a Mikrotik. So just add an IP to the Mikrotik’s LAN port that’s on the same subnet as the Sonicwall.
Ok hopefully I can explain this clearly… Sonicwall is on 192.168.1.X Mikrotik is on 192.168.128.X both of them are connected to the same switch.
Now is where I am having the issue.. I have Grandstream VOIP phones that are on the 192.168.128.X subnet and they can all talk to the Mikrotik… and the computers are connecting through the phone’s PC port, and the computers are all on 192.168.1.X but for some reason they cannot talk to the Sonicwall. If I bypass the phones and plug the computers right into the wall jack then all the computers can see the Sonicwall again. The computers are all using gateway 192.168.1.1 and all the phones are using gateway 192.168.128.1.
Even when I added a 192.168.1.X address to the Internal bridge on the Mikrotik I still can’t talk to the Sonicwall.
Are you sure there aren’t any VLANs configured on the switch?
If your subnets are on different VLANs you need to make sure the pass through ports on your phones are on the right VLAN, which in this case is probably a different VLAN to the one the phones themselves should be on.
It’s common in this kind of setup for the phones to be on one VLAN and the desktops to be on another.
If your PC’s get an IP and can ping the Sonicwall when plugged into the wall port directly but not when plugged into the pass through port then it has to be an issue with the pass through ports.
I’m not familiar with Grandstream handsets but I have come across configs on IP phones that disable the pass through ports or forces them to use a particular VLAN.
If the Mikrotik and the Sonicwall are definitely on the same physical network; you’ve added a 192.168.1.x address to the Mikrotik on the interface that’s attached to that network and you can’t ping the Sonicwall from the Mikrotik but your desktops can ping the Sonicwall, then they either aren’t on the same physical network or they are separated by VLANs you’re not aware of.
