Hi all,
A couple issues came up after installing our new 5510, a couple sites that uses the same ISP as our's had issues, one where we can email them but their incoming to us wasn't working, and another site we couldn't browse on the web.
This all worked after putting back the old firewall. I was wondering and it might be a dns issue with our isp's and the asa could be blocking on the outside int, on the old firewall I have the trust to untrust allow dns outgoing, that setting is not on the asa since it's inside int has 100 rule. I also talked to the IT dept of the site that had incoming email issues, he said 2 of their Exchange servers are connected to the same isp as ours, most sites worked and email, but there might be more we just haven't tried yet. For now I have our old firewall till I figure out what's causing some sites to not work on the asa.
update - I added my object group DNS-SERVERS on the outside int, I'll test again to see if the sites in question works
here's my latest config, thanks in advanced.
