VLAN configuration for access with vnc

Locked

HI
We have a watchguard firebox x500 without installed and configured by an external company.
It is connected to a nortel baystack 450 switch in the default VLAN1.

Now we have created a second vlan with that has 2 ports (for 2 computers) and they have to be isolated from the network but have to be accessable with vnc over the internet.

I added the firewall port in vlan 1 and 2.
Everything works fine for vlan 1. But in vlan2 the computers can only ping each other and nothing more.

Every port is configured default with untagged access. When I change the firewall port on the switch to tagged trunk, nothing works.

How do I need to configure the ports for the vlan?
How do I need to configure the firewall?

default gateway

In reply to VLAN configuration for access with vnc

If you create to vlans you need to create 2 default gateways on your router in order for it to properly work. You need to use something like 192.168.1.1.1.

I believe and then for the second vlan do the same except
192.168.1.1.2

This is because both VLans can not communicate together therefore may not use the same default gateway.

I cannot remember exactly how to segment your default gateway on the router so you would have to look that up.

Any other questions post back!!

It’s a layer 2 switch, not a router, and I don’t know what or how you mean with setting a default gateway.

I think I have to change something to the firewall but I don’t know what exactly

Router

In reply to don’t understand

Does the switch get connected to a router?

Because if it does the second vlan will not be able to be accessed from any other device. Untill the default gateways are set up correctly.

Except of course other device on the same vlan on the same switch.

network plan

INTERNET—FIREWALL—SWITCH with vlan 1 (everything except 2 ports) and vlan 2 ( the 2 ports and the firewall port)
