I have a fairly basic question. I'm currently in the process of swapping carriers from internet services. (I will be making changes on my asa 5510 outside)
I want to change my outside static to the new internet services static ......and just want to be clear on the ramifications.
the only things I have currently configured in my security policies are 1) allow |source "any"| to |destination "outside"| ..services are https, 3389,smtp, and pcanywhere....so these will be fine IMO with the change over to the new outside static...no big deal.
here is where i'm a little gray... I have 3 other security access rules created for static addresses tied to a domain for web access. For example: my exchange with OWA is accessed over the web. The domain is tied to an outside static (ex. mail.domain.com = 220.127.116.11) ..users can access over https.
In my asa I have that set up as: allow|source "any"| to |destination "18.104.22.168"| service http currently.
...when I spoke to the ISP that handles my domains (this is the internet service I will be leaving, but they will still host my domains)..he mentioned that it should be no problem since i'm just changing the outside static = internet...the site should still propagate down from the outside world to through the asa b/c of the acl and nobody will even notice the change.....the only thing I would need to change is the VPN .pcl file for vpn users.
Does this sound accurate or am I overlooking something.
