What needs to be changed in our firewall when changing ISPs?
Posted on 2013-09-11
Hello. Tomorrow my company is switching from Cbeyond to Comcast. Now of course when Comcast is doing the sales pitch they tell you how they take care of everything and the cutover is painless, etc. etc.
Yesterday afternoon they told me that they will not make any of the config changes on the firewall to accept the connection. Our usual guy who does the network security is NOT available. My question is....what needs to be changed on our Cisco ASA 5505 and exactly how can I change? Comcast is giving us 5 static IPs. One of my colleagues told me they have a friend who can load our backup config into a configuration maker and send us the new config to just load in there but now he is on vacation.
Any help you all can give would be great because now we are scrambling!
