No,

Just moving the asterisk-server before the firewall won;t do any good.
because in that situation the firewall is in between asterisk and your
LOCAL sip-clients: you just solved one problem by introducing another
eg, the just moved the problem to another place....

What you can do (perhaps not the best solution...) is having one
asterisk server behind your firewall, serving all your local
sip-clients. And another at the other side of the firewall, only for
serving remote clients. And have both systems talking to each other with
IAX instead of SIP....

In that case you _only_ have to allow port 4569 for IAX instead of 5060
and 10000...20000 for SIP
