[nn] Vlan Tagging and DHCP

[hboogz <hboogz@gmail.com>]

Hi all,

I currently have a netscreen 5GT terminating to a checkpoint FW-1 firewall using an ipsec vpn tunnel.

Behind
the checkpoint there is a central DHCP server. Behind the netscreen we
have Cisco 1130 AG access points deployed and the netscreen's DHCP
function is set to DHCP-relay.

The issue i am having is, when i
introduce a second guest SSID, i want that SSID to map to a different
VLAN. i have done the necessary config on the Cisco AP, but can't seem
to get an IP for the second VLAN i've defined.

Central Office - 192.168.1.x

Site office - 192.168.8.x

Vlan1 gets an ip from the central office's DHCP scope 192.168.1.x

Vlan2 - 192.168.254.x

Now,
what needs to be done on the netscreen in order for it to receive the
vlan 2 tag in order to issue an IP from the vlan 2 scope defined on the
switches and dhcp server at the central office ?

any ideas would be great.

I'm
thinking if i define a sub-interface on the netscreen with vlan 2 tag
and somehow issue a udp-helper command for that interface to point to
the dhcp-server 192.168.1.x -- ?

Thanks,
