Hi, Final update to my problem:
I dropped the Netgear switch and used a Linksys^H^H Cisco switch. The Linksys worked right out of the box. Netgear's tech support lead me nowhere... I opened a support ticket and someone acknowledged that it was too complex for Level 1 support and escalated itto Level 2. That's the last I heard from them... Netgear, I say boo! I suppose this is simple for many folks, but I found this pretty hard (atleast in the begining). Should anyone care, here is the complete solution I use for inter-VLAN routing: Physical connections on the switch: port 1: network A -- 192.168.1.0/24 port 2: network B -- 192.168.2.0/24 port 24: obsd router Switch vlan setup: vlan1: port 1 (untagged), port 24 (tagged) vlan2: port 2 (untagged), port 24 (tagged) On the obsd box, run ifconfig fxp0 up ifconfig vlan1 vlan 1 vlandev fxp0 192.168.1.1 255.255.255.0 up ifconfig vlan2 vlan 2 vlandev fxp0 192.168.2.1 255.255.255.0 up Finally, enable IP forwarding and adjust pf.conf to suit. Note that the obsd box uses only a single physical NIC. The virtual vlan interfaces appear like real interfaces to most networking systems like pf, and user land apps (and this can be exploited in situations where there is a physical constraint on the number of NICs you can add to a machine). Using a 1000BT connection between the switch and obsd box is recommended. Only the obsd box and the switch need to be VLAN aware. To avoid MTU headaches and other incompatibilities, you must choose a NIC that supports VLANs -- fxp, xl, sis, and the usual suspects. The setup is totally transparent to all other devices. Thanks to all who helped me through this. Especially Brian Shakelford and Camiel Dobbelaar. Thanks guys! - Raja On 5/17/06, Raja Subramanian <[EMAIL PROTECTED]> wrote:

An update of my situation: I'm able to use the default mtu of 1500 bytes on both sis/fxp without any issues. In my current setup it seems that my switch does not permit the same MAC ID (of my router NIC) to appear on different VLANs. So long as I have only one vlan interface up at any given time, everything works perfectly. Many thanks to Camiel Dobbelaar (who IMO is worth Marlon Brando's weight in diamond studded platinum) for all his patience and guidance in helping me track down this issue. :-) - Raja PS: I'm sorry to spam the list with this problem. It seems more like an issue with my switch rather than obsd.
