[Users] openser on host without public IP

[j.obi at troja.net]

Hi

Is it possible to use openser on a host without a public IP address?
I have a router by my internet provider for the SDSL connection and behind
that a wrt54g with openwrt on it. That works as Firewall and I want to use
it as sip proxy now too.
My Question is now, are there any possibilities to use openser with stun
or something similiar to work around the problem with the IP address?

Bye Jens
