Re: Can I assign multiple outside IP ranges to my 5505?
I am in the process of migrating our existing IP subnet from a /29 to a /27.
Is there a way to assign the new /27 IP addresses to the same outside interface on my 5505 as the existing /29 and run them parallel while I transfer DNS for www, smtp, etc?
Is the subnet the same IPs just with a bigger subnet mask ?
If so do you mean you have actually assigned DNS/WWW/mail servers with public IPs ? If there are using private addressing and then being natted to a public IP then the change of subnet mask shouldn't affect them at all. You would only need to change the subnet mask on the outside interface.
