WAN IP Change on ASA to do list
Posted on 2014-02-22
We will be changing offices in the next week or so and will be getting a new public IP address and NAT block range. Currently we have an Cisco ASA.
Having never done this before I am wondering what are the things that need to be changed? Below is a list of things that I think need to be done, please let me know if I have got any of them wrong or if I am missing a step or something procedural. I am specifically worried about what effects the change will have on VPN access for remote clients.
1. Change the IP address of the outside interface to our newly assigned public IP address from within the interfaces section of the ASDM interface.
2. Change to the new WAN gateway IP address under the routing - static routes-gateway IP section of the ASDM.
3. Change all of our current NAT & ACL listings to map to new NAT block we have been assigned as well as change the associated DNS listings.
4. Create a new .PCF file based on a modified version of one of our existing client VPN files, by simply changing the IP address to the newly assigned outside interface WAN IP.
5. Provide that .pcf file to all of our client computers.
Do I need to reconfigure anything as it relates to the VPN on the ASA side it's self, or is it simply pcf client side updates?
Does that all seem correct? Is there anything I am missing? If so please let me know.
Thanks for the help:-)
