Hi,
I have a question about configuring VLANs and I hope you can help.
In the office we got a 3com baseline 2916 SFP plus switch and a 3Com wireless 7760 accesspoint. For internet access we use a draytek 2820 router and also a VMWare ESX server is installed with several virtual servers running on it.
The configuration is as follows:
- The router is configured to use VLAN 2 and 3 and is connected to port 15. This port is configured untagged for vlan 2 and tagged for vlan 3. The router is a DHCP server (192.168.0.x). (tech specs:
- The server uses vlan 2 for internet access and no vlan is set up for the local network. It is connected to port 16 on the switch which has vlan 2 tagged and vlan 1 untagged. One of the virtual servers is a DHCP server for the LAN (10.0.0.x) and also routes between the lan and the router.
- The accesspoint is capable of multiple SSID's with each SSID on a separate VLAN. It also supports a management VLAN.
SSID1 uses VLAN 1 and SSID2 uses VLAN 3. It is connected to port 8 which is configured tagged on VLAN 3 and untagged on VLAN1.
I try to create a situation in which my accesspoint is configured with two SSID's: one to have lan access and one to have internet only access. This last one is for clients or partners to have guest access.
The current problem with the situation is that when I subscribe to SSID2, i get a 10.0.0.x IP although VLAN 3 should get an IP address from the router (192.168.1.x)
Does anyone have a clue how i should configure the switch so i get the right dhcp response in vlan 3?
Also: I noticed when I change port 15 (router) from untagged to tagged in VLAN 2, the server can no longer connect to the router.
Please feel free to ask for more information, i will try to give a quick response.
