VLAN Routing for Newbies
Howdy All, I've recently decided to install a GS752 switch in our offices to segregate traffic to help with security. I've run into a problem that I'm hoping someone can help me with (to keep th...
Another QUICK question:
ALL of my ports in ALL VLANS are "U"ntagged.
VLAN 1 - U - Ports 1-10
VLAN 10 - U - Ports 1, 11-25
VLAN 20 - U - Ports 1, 27-39
VLAN 30 - U - Ports 41-47 (Isolated)
ALL of my ports in ALL VLANS are "U"ntagged.
VLAN 1 - U - Ports 1-10
VLAN 10 - U - Ports 1, 11-25
VLAN 20 - U - Ports 1, 27-39
This looks like a highly illegal configuration to me. The same port 1 can't be in multiple VLANs as [U]ntagged.
Do you expect that any outgoing frames for all these VLAN 1, 10, and 20 can come out of the port 1?
What have you set for the PVID defining the VLAN where incoming frames to port 1 will be assigned to?
This looks to me like an asymmetric VLAN config - something Netgear does not support at all.
Thanks for the reply... in re-visiting some of my pre-planning documentation I found that yes, the port SHOULDN'T be assigned... Changes below to simplify and help me....
VLAN 1 - Ports 1&2 [Port 1 - 10.1.10.10, Port 2 - Empty]
VLAN 10 - Ports 3-10 [10.0.10.0/255.255.255.0]
VLAN 20 - Ports 11-26 [10.0.20.0/255.255.255.0]
VLAN 30 - Ports 27-39 [10.0.30.0/255.255.255.0]
VLAN 40 - Ports 40-52 [10.0.40.0/255.255.255.0]
I've got the switch reconfigured and this seems to be working that VLAN1 can see things, but still haven't gotten traffic from VLAN 10, 20, or 30 to reach OUTSIDE of the switch. I've crated ACLs under security following a Netgear article, but no change..
What I'm trying to get now is as follows:
VLAN 1 & 10 - External DHCP from the Firewall to be "Internal DMZ"-esque
- This works on VLAN 1 but not to VLAN10
VLAN 20 - Routing through VLAN 1 or 10 to the outside world
- Also routing to VLAN 30 as I will be connecting from my system to the classroom systems for maintenance
VLAN 30 - Routing through VLAN 1 or 10 to the outside world
VLAN 40 - Only local traffic, cordoned off if I need a test environment
If anyone can help me
