PPP connection created by SonicWall NetExtender on Ubuntu 20.04

gb flag
Alfredo Tostón

I'm trying to connect to the client VPN via Sonicwall NetExtender. On Windows there is no problem, but I cant't connect on my Linux Desktop (sometimes it works, but it's the exception).

When I connect everything seems to be ok, but the result is as if it's not connected. If I do a ip a on the console I can see the ppp0 connection created,

20: ppp0: <POINTOPOINT,MULTICAST,NOARP,UP,LOWER_UP> mtu 1280 qdisc fq_codel state UNKNOWN group default qlen 3
    link/ppp 
    inet 192.168.200.200 peer 192.0.2.1/32 scope global ppp0
       valid_lft forever preferred_lft forever

Can I assume the problem is related to that 192.0.2.1/32? The provider IP is not that, but may be its local addreess. If it's so, how can I change the ipcp-accept-remote flag of the ppp connection created by the NetExtender client? Can I even change it after the connection is created?

Edit 19/07/21:

I've tried disabling NetworkManager with no effect. Then I've enabled debug logging of NM and got this:

Come to my attention the following lines:

Jul 19 21:01:21 this-machine NetworkManager[11584]: <debug> [1626724881.8718] platform-linux: error reading net:/sys/class/net/ppp0/phys_port_id: error reading 4096 bytes from file descriptor: La operación no está soportada

Am I missing something?

PPPD is in my mind usually not a VPN .-) and i belive you setup your VPN Worngly, as i belive that 192.0.2.1 is not owned by you and is imho not reserved for LAN usage. change or update it to 192.168 or 172.16 or 10.

I've tryed some remotes with `ifconfig ppp0 pointopoint XXX.XXX.2.1` and even the public IP of the provider and I'm still with no network connectivity. May the change require some other configuration? Unfortunately I have no access to a configuration file of the created ppp cause it's configured dinamicly by the NetExtender client. Nevertheless, I'll try to ask some coworkers about the real IP I need. Thanks.

I've verified the original IP with a working Windows client.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
