Quick setup question. I have a circuit delivered to me via RJ45 drop from ISP. I have my end terminated into a 3640 router FastEthernet Port FA0/0.
description LightPath CKT - 06ZZX1800078
ip address 22.214.171.124 255.255.255.252
ip nat outside
The above is our connect to their router. To bring the bandwidth in to my users, i have configured another FastEthernet Port on same router which temrinates into our FW. I used one of our global IP's and assigned it to FA0/1 as indivated below.
description LINK TO NSA3500 WAN <GATEWAY>
ip address 61.x.x.x 255.255.255.224
The other side of this as mentioned terminates into our firewall with another global ip assigned to that interface which is the GW for my users. This is all working fine buy I want to know if this is the "correct" way to accomplish this.
