CISCO router 506e question

I have a CISCO router 506e that been running fine for over 6 months. Until two days ago, I was able to access the internet from the server and from 8 other workstations. The CISCO router is connected thru to a 24port switch. The servers and other worksations are connected to the 24 port switch. If I remove connection 0 and 1 from the router and connect them directly to the internet, I all machines including the server are able to access the internet. A friend told me the PIX configuration needs to be changed, but I'm not sure where to make the change. I did notice the following from the PIX configuration. no fixup protocol ftp 21 no fixup protocol http 80 I believe they correct setting should be: fixup protocol ftp 21 fixup protocol http 80 However, I can't find the command to change it. I've tried entering the following at the command line without sucess: fixup protocol ftp 21 fixup protocol http 80 ## Deliverables 1) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done. 2) Deliverables must be in ready-to-run condition, as follows (depending on the nature of the deliverables): a) For web sites or other server-side deliverables intended to only ever exist in one place in the Buyer's environment--Deliverables must be installed by the Seller in ready-to-run condition in the Buyer's environment. b) For all others including desktop software or software the buyer intends to distribute: A software installation package that will install the software in ready-to-run condition on the platform(s) specified in this bid request. 3) All deliverables will be considered "work made for hire" under U.S. Copyright law.
