Firewall external IP address info.

Happy new year.
I have been given the below ip information from BT and need to configure two firewalls.

I have set one firewall with
IP : 194.72.126.66/28
GW : 194.72.126.65/28

Which seems to work great but I'm struggling to get the second firewall working what should the IP address and Gateway be for the second firewall?

Below is the info I got from BT

  194.72.126.64/27
 
HSRP 194.72.126.65
PRI NTE LAN 194.72.126.74
SEC NTE LAN 194.72.126.75
 
  194.74.139.64/28
 
HSRP 194.74.139.65
PRI NTE LAN 194.74.139.66
SEC NTE LAN 194.74.139.67

Hi,
the easiest way ti find it out is to plug your laptop into the switch where the ISP router is plugged into and give your laptop a suitable address.

I'd begin with setting 194.74.139.68 to ypur PC and set 194.74.139.65 as default gateway.
If it goes through internet, you can give 194.74.139.68 to your firewall. You should at least be able to ping 194.74.139.65 successfully.

The info sent by ISP seems to be inaccurate, but with some testing you may succeed in finding it out.
Otherwise you will have to call them again

hope this helps

Well, the first usable address in your case would be 194.74.139.68 (since 66 and 67 are allocated) with 194.74.139.65 as the default gateway. So if that that is what you want to make the address on your firewall, that would make sense.
