Default route issue

Hi *,

 

I'm using PulseSecure v. 22.2.1.1295 on Linux (Lubuntu 22.10). I can successfully establish a VPN connection, but my traffic does not get routed through the VPN.

 

It seems to be an issue with the default route, which is still set to my public IP:

(base) ➜  ~ ip r
default via 192.168.1.1 dev wlp3s0 proto dhcp src 192.168.1.4 metric 600 
130.223.xxx.xxx via 192.168.1.1 dev wlp3s0 metric 600 
192.168.1.0/24 dev wlp3s0 proto kernel scope link src 192.168.1.4 metric 600 
192.168.1.1 dev wlp3s0 scope link metric 600

 

What can I do to fix this issue?

 

Thanks.

Re: Default route issue

are the internal resources on the same network (192.168.1.0/24)?

Re: Default route issue

I am actually not sure what the 168.192.1.0/24 is about... Maybe it is related to the problem?

 

"ip a" gives me this:

(base) ➜  ~ ip a 
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1000
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00

    link/none 

("tun0" is the device set up by Pulse Secure, I wonder why it has "state DOWN"...?)

 

When I disconnect the VPN connection, the alternative route is still there:

(base) ➜  ~ ip r
default via 192.168.1.1 dev wlp3s0 proto dhcp src 192.168.1.4 metric 600 
192.168.1.0/24 dev wlp3s0 proto kernel scope link src 192.168.1.4 metric 600

Re: Default route issue

i am not sure what may be causing that
i would recommend opening a case with our support team to check
