firewall a T1 connection
we have a t1 conection which we want to firewall
the T1 router has an ip address of 172.30.10.x
we pluged the t1 connection to our firewall and dont know which ip mask and gateway to configure on the firewall interface for this connection
our goal is to allow a internal server on the lan 10.10.100.x to be natted as 172.50.20.x and go through the T1 connection
do we assign the firewall interface a 172.50.20 address or does it need to be a 172.30 .10 (same as t1 ip)

If you want lan 10.10.100.x to be natted as 172.50.20.x, 172.50.20.x has to be allow to use by T1 provider.
If you firewall is cisco, You can check the ARP table and see what the next hop is
#show arp
Hope this help,

Contact your T1 provider and request the TCP & DNS information. they should have provided you with that when they installed the T1.
I install T1's for a major company and that is standard practice.
