I have a problem when using NetworkManager to connect to VPN
connections, on an up to date fedora 11 system.
I previously (ubuntu gutsy) used to connect to a vpnc (VPN Compatible
Cisco) server with the command line tool.
Using the command line still works with Fedora 11. When I try to switch
to the NetworkManager builtin VPN manager, I manage to connect to the
remote VPN server, but no network activity can be made. It s maybe a
problem with the routes.
When connecting to the VPN with the vpnc command line tool, no specific
configuration (but the group & user login/password) is defined. No
specific routing configuration has been made.
192.168.246.254 is the gateway of the LAN.
62.39.X.X is the remote VPN server.
[root@axel-asus axel]# LANG="C" netstat -ren
Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use
Iface
62.39.X.X 192.168.246.254 255.255.255.255 UGH 0 0 0 eth0
192.168.246.0 0.0.0.0 255.255.255.0 U 1 0 0 eth0
192.168.122.0 0.0.0.0 255.255.255.0 U 0 0 0
virbr0
0.0.0.0 0.0.0.0 0.0.0.0 U 0 0 0 tun0
The tun0 adapter address becomes 10.240.200.10/255.255.255.255
I manage to access to remote hosts (10.240.0.0/16 range). In other
words, out-of-the-box vpnc tool works well.
When connecting with the NetworkManager, the routing table is different :
[root@axel-asus axel]# LANG="C" netstat -ren
Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use
Iface
62.39.X.X 192.168.246.254 255.255.255.255 UGH 0 0 0 eth0
192.168.246.0 0.0.0.0 255.255.255.0 U 1 0 0 eth0
10.240.200.0 0.0.0.0 255.255.255.0 U 0 0 0 tun0
192.168.122.0 0.0.0.0 255.255.255.0 U 0 0 0
virbr0
0.0.0.0 0.0.0.0 0.0.0.0 U 0 0 0 tun0
And the netmask of the tun0 adapter is different too :
10.240.200.10/255.255.255.0
And I cannot access 10.240.0.0/16 hosts.
"ignore the routes" option is unchecked, "only use the connection for
same network resource" option is unchecked, both in "IPv4 Settings" tab,
"Routes" button. I tried to check them, both, and only one, without
successful result, though the routing table is different for each setting.
So is there something wrong in my NetworkManager settings ?
Thanks for your help.
