New router and registration problems

I just set up a WRT54GS and now I can’t dial out or in.

sip show registry shows:

Host dnsmgr Username Refresh State Reg.Time N xxxxx 120 Request Sent

I seemed to recall that running in cli always showed a response back, but there’s nothing now. Using
I have my number at draytel set up to dial my mobile if asterisk is down and it keeps doing it as if it’s down.
I setup my server as DMZ in the router, as my old one was. Tried with firewall off.

Any ideas?

Well I don’t know why, but I stopped asterisk for a few minutes and when I restarted it it registered. So all working again.
