Using a block of IP's without applying them to an interface
Posted on 2004-11-21
This question has been asked before as PART of another question previously posted.
I've been issued a block of public ip's 188.8.131.52 /25 to 184.108.40.206 /25 - Labled as "Ethernet/lan" by the isp
I've been assigned 220.127.116.11 /30 labled as " WAN IP"
I called the ISP as I want to nat the public IP's to internal addresses on a cisco 2620. I was told to apply the 18.104.22.168 to S0 and apply 192.168.1.1 to E0. In other words, do not apply the 57.X.X.X address to any interface and just nat them the same way I had before.
ip nat inside source static tcp 192.168.1.10 80 22.214.171.124 80 extendable <-- for www server
1. Will this work as described and/or is there anything else that I need to do like adding the 57.X.X.X network as a static entry?
2. Do I need to specify the ISP's router address (126.96.36.199) anywhere on the router as a gateway?
I was told that I don't need to be concerned with the 57.X.X.X network as it is an entry on the ISP's routers but this was information by an engineer who was in an obvious hurry and felt that since we did not buy the router from them that it was some sort of "privilage" for me to ask any questions at all. Question 3. I can still cancel. Should I even bother setting up service with this ISP?
Thanks for your help!
