I have a client who has moved offices and has a dsl account with ATT. ATT gave us 5 static IP's which are 99.*.*.73 thru 99.*.*77 and the gateway they gave me is 99.*.*.78. The trouble I'm having is that when I program the ASA to use one of the static IP's and the gateway I can't access the internet. When I program the ASA to automatically aquire the ip then my IP becomes the gateway and websites report my Ip as being the gateway. I've never seen this before. I can even RD in from the outside by going to the gateway address, which the att tech tonight said I shouldn't be able to do. How is this possible? Should I just let the asa aquire the ip and route automatically and then make access lists for the static ip's? What if I had an Exchange server behind the router and it had to to have one of the static ip's? If the email was coming from a different ip than what the mrecords were showing then wouldn't I have problems?
Any help someone could be would be much appreciated. I have had nothing but troubles the last two weeks with ATT and feel like they haven't given me correct information even though I have called and verified our addresses with them.
Thanks in advance,
