I haven't found that to be a problem, I run shorewall on my pbx 
machines, I allow IAX externally, SIP and RTP internally, ftp and http 
for monitoring and phone configs, I have zero problems with this 
configuration. Putting the PBX on the internet feed avoids a lot of 
issues with NAT.
If I were doing multiple servers and a huge corporate network I would 
not do this but for a 10-100 user one location company, this is 
perfectly workable.
