Buongiorno a tutti.
Ho il seguente problema: ho configurato un bilanciatore di rete che smista il traffico su diverse linee ADSL. Il bilanciatore è un ENDURALINK ER-1088.
Per tutte la connettività non VPN non ho alcun problema.
Per quanto riguarda la connettività VPN ho invece questi problemi:
. Se testo la connettività da un link BT mi collego senza problemi
. Un dipendente si collega da casa con usando un link Wind Infostrada senza problemi
. 2 dipendenti non riescono a collegarsi da casa e usano Alice
I dipendenti che non riescono a collegarsi mi hanno postato dei log dai quali si evince che la fase 1 viene completata in modo corretto ma la fase 2 non arriva a compimento e il tunnel cade.
La configurazione è di questo tipo:
LAN 10.0.0.0 ---> 10.0.0.251 PIX 10.1.1.1 ---> 10.1.1.254 BILANCIATORE IP PUBBLICI ADSL --> ROUTERS ADSL
Il nat-traversal è abilitato.
Posto la configurazione del pix:
