IPsec tunel nefunguje

[noger]

Zdravím Vás, obraciam sa so žiadosťou o pomoc pri konfigurácii ipsec tunela medzi dvomi spločnosťami.

Skusil som nasledovné:

V prílohe sú technické parametre ipsec vpn

Ipsec som nikdy nekonfiguroval a ani s nim nemám  žiadne skúsenosti.

Ked zadám

Kód: [Vybrat]

ipsec auto --up Alt tak mi ostane kurzor blikat a nic sa mi neudeje.
Vopred ďakujem za akúkoľvek pomoc

Protokol ESP a udp/500 je povoleno?
Pripadne zmenit parametry sifrovani (3DES,DES,..).

Ahojte, dakujem vsetkym za intervencie. Nizsie je kratky sumar funkncej konfiguracie

Potrebne baliky:
ipsec-tools
openswan

Problem bol jednak v mojm konfiguraku, tak aj na strane vpn koncentratora.

Funknce pripojenie VPN :

/etc/ipsec.conf

Kód: [Vybrat]

cat /etc/ipsec.conf
