PIX (VPN) + DNS Zone Transfer

[alan]

Ciao a tutti.

In breve il mio problema è questo.
Ho due LAN collegate in VPN attraveso un PIX 501 ed un 506.
La VPN funziona alla grande, ping, risorse di rete, ftp, telnet ... insomma nessun problema.

Oggi vado ad utilizzare il zone transfer tra i 2 DNS (WINDOWS 2003 purtroppo) delle due reti ... niente. Mi dice che l'uno non riesce a contattare l'altro.

Qualcuno ha qualche consiglio a riguardo?

Come sempre grazie mille!

Ciao,
potresti postare la configurazione di ambedue i pix e i router, altrimenti sarà difficile diagnosticare il problema.

Saluti

Ciao marchino65

Di seguito la configurazione dei due PIX. In pratica sono identiche ... cambiano ovviamente i riferimenti delle LAN.
Intanto grazie mille ...
