We have isa 2006 EE Array with 2 node on win2003 sp1.configure as
node 1. nic 1( Internal ) 192.168.1.*/24, nic 2 ( DMZ) 192.168.5.*/24, nic 3 ( External) 192.168.50.*/24, Intra Array nic4 90.0.0.1
node 2. nic 1( Internal ) 192.168.1.*/24, nic 2 ( DMZ) 192.168.5.*/24, nic 3 ( External) 192.168.50.*/24,Intra Array nic4 90.0.0.2

VIP Inernal 192.168.1.5/24 , DMZ VIP 192.168.5.5/24 ,External VIP 192.168.50.5/24

i want to anyone from internal to connect to DMZ server should go to isa internal VIP as gateway ( i done this on my router) and from DMZ anyone want to go to Internal Network use External VIP as Gateway.

i configure on ISA Network Rule as Routeing between 2 netwok ( int-Dmz) and also make Access Rule to allow ping frm some Server to DMZ and Viceversa

but this is not working i can ping to isa External int. frm my internal network but nothing on DMZ and  same frm DMZ i can ping isa Int. interface but nothing inside.

when i remove NLB form Int. and DMZ and kept node1 or node 2 Phisical ip as gateway its work i can ping DMZ server and from DMZ i can ping Internal server (i configure Rule to allow ICMP and some Port to communicate with my backup server) but when i enable NLB its stop working..

What could be wrong?

here with correction.

We have isa 2006 EE Array with 2 node on win2003 sp1.configure as
node 1. nic 1( Internal ) 192.168.1.*/24, nic 2 ( DMZ) 192.168.5.*/24, nic 3 ( External) 192.168.50.*/24, Intra Array nic4 90.0.0.1
node 2. nic 1( Internal ) 192.168.1.*/24, nic 2 ( DMZ) 192.168.5.*/24, nic 3 ( External) 192.168.50.*/24,Intra Array nic4 90.0.0.2

VIP Inernal 192.168.1.5/24 , DMZ VIP 192.168.5.5/24 ,External VIP 192.168.50.5/24

i want to anyone from internal to connect to DMZ server should go to isa internal VIP as gateway ( i done this on my router) and from DMZ anyone want to go to Internal Network use DMZ VIP as Gateway.

i configure on ISA Network Rule as Routeing between 2 netwok ( int-Dmz) and also make Access Rule to allow ping  and some more ports frm some Server to DMZ and Viceversa

but this is not working i can ping to isa External int. frm my internal network but nothing on DMZ and  same frm DMZ i can ping isa Int. interface but nothing inside.

when i remove NLB form Int. and DMZ and kept node1 or node 2 Phisical ip as gateway its work i can ping DMZ server and from DMZ i can ping Internal server (i configure Rule to allow ICMP and some Port to communicate with my backup server) but when i enable NLB its stop working..
