Basically I used the example from the Asterisk book "Connecting Two Asterisk Boxes Together via 
IAX" and there is not a lot to see:


; Server A
[general]
;           this box            remote IP
register => ServerA:very_secret at 80.152.xxx.xxx

disallow=all
allow=alaw
allow=ulaw
allow=gsm

jitterbuffer=no
forcejitterbuffer=no
autokill=yes


; the other box
[ServerB]
type=friend
trunk=no
auth=md5
encryption=yes
secret=very_secret
context=from-ServerB
qualify=yes
host=dynamic
; end of Server A


; Server B
[general]
;           this box            remote IP
register => ServerB:very_secret at 79.233.yyy.yyy

disallow=all
allow=alaw
allow=ulaw
allow=gsm

jitterbuffer=no
forcejitterbuffer=no
autokill=yes

; the other box
[ServerA]
type=friend
trunk=no
auth=md5
encryption=yes
secret=very_secret
context=from-ServerA
qualify=yes
host=dynamic
; end of Server B

If I replace the WAN addresses of the two routers with addresses on the LAN, everything works. 
Currently, I am not sure whether it could be a NAT related or Asterisk configuration problem.
