i want to pass all my users out my internet pipe on the same NAT/PAT address
at the moment i have all users behind a firewall which passes traffic to the perimeter router (the firewall's external ip is a private address & non routable)so the router's external IP is the address i present to the internet
i have implemented a PAT solution on the external interface and access to the internet is working but i thnik i remember reading that PAT doesn't like streaming, VoIP etc and this would match my problem - when i access some sites with streaming content it hangs
should i use a nat solution instead but rather than use a pool of addresses (which i don't have) just use the external interface's IP?
thanks to anyone taking the time to reply
ps - any links to configs are greatly appreciated
hope this finds you all well
