VPN Problems with Sonicwall Gen. 7 Firewalls
I am experiencing a lot of problems with all kind of VPN tunnels when I upgrade to version 7.0.1-x5xxx.
In v 7.0.1-R5018 and higher I have problems with site-to-site tunnels: they don´t connect any longer. After downgrade everything is allright again. So it is definitely not a configuration problem.
In v 7.0.1-R5018 and higher I have a problem with VPN over L2TP: It is possible to establish the tunnel, but no devices on the specified subnet is reachable. Management of the firewall is possible.
In v 7.0.1-R5008 and higher I have a problem with SSLVPN: It is possible to establish the connection, devices on the specified subnet are reachable, but management of the firewall isn´t possible. Neccessary rule is configured.
It is no longer possible to have a site-to-site tunnel parallel to a L2TP-Session. In former times this was a convenient way to configure the firewall without loosing connection if I made an error.
Most devices are secure upgrades from former Gen 6 models.
Are these common known problems or ist this only on my configurations/devices?
