broadcast udp 139 through PIX (6.3.3)

Hi,

I have trouble to replace a router with a PIX.

In the PX-525 I have 3 VLAN.

vlan1: client windows

vlan2: dhcp/dns server (CNR) + BDC

vlan3: PDC

With the "dhcprelay" command i have not problem with the DHCP server in vlan2.

But I need to forward udp broadcast port 139 in order to change windows password on PDC in vlan3.

In the router all is ok with this command:

ip forward-protocol udp 139

ip helper-address <IP DHCP server>

ip helper-address <IP PDC>

thanks

Re: broadcast udp 139 through PIX (6.3.3)

you will need to make sure there is no nat between subnets. you will want to allow udp/tcp 42,88,135, 137,138,139,445 in and out between all the vlans.

MS networking does not play well with firewalls between segments
