[ekiga] pas de connexion

Bonjour,


Ekiga n'arrive pas à se connecter: j'obtiens le message d'erreur suivant:

Ekiga did not manage to configure your network settings automatically. You can still use it, but you need to configure your network settings manually.

Please see http://wiki.ekiga.org/index.php/Enable_ ... g_manually for instructions

Je soupçonne mon firewall (configuré d'après le wiki d'arch https://wiki.archlinux.org/index.php/Si ... l_firewall) de tout bloquer, mais mes bidouillage n'ont rien donné. J'ai pourtant essayé d'ouvrir les protocoles SIP, H323 et STUN en ajoutant quelques règles, en vain.
un iptables -L donne:

Chain INPUT (policy DROP)

Merci d'avance!

EDIT: ce n'est pas nécessairement un problème de firewall, parce que cela bloque aussi sur opensuse où le firewall est à priori différent
