Pulse Secure VPN - split tunneling enabled breaks users internet

When I enable Split Tunneling for a vpn profile any users on that profile can no longer use the internet on their device/computer. I’m testing it. DNS actually works, I can resolve internet and work DNS names. but I can’t ping 8.8.8.8 when split tunneling is enabled. It’s strange. Clearly I have a misconfiguration somewhere.

We are using a Pulse Secure Appliance. any help would be appreciated. I’m waiting for the Pulse team to pick up my ticket.

EDIT FIX: (split tunnel was only not working on iOS and Android) fix below:

add dummy IPv6.

I really hate PulseSecure and my college mostly do the work with maintaining it - lucky me.

I’m not sure on how to fix your issue, but maybe see if debug mode can be turned on or look at the logs. If it works when spilt-tunnel is disabled and not working when enabled, it might be because of a routing issue??

Hope this helps a bit and good luck :wink:

added “dummy” IPv6 info. problem solved. crazy. I can’t believe I stumbled across this KB.

What subnet do you use for work? Could it be colliding with whatever subnet home users have?

If for instance your work network is on 192.168.0.0/24 it would collide with the vast majority of consumer network equipment. This would likely lead to routing issues which could cause the exact problem you’re describing.

We use Pulse (and I love it), we don’t use it for our mobile devices however.

Still good to know in case it pops up somewhere.

Thanks for the update.

thx for try… I added fix to post

I really hate it, especially their Linux client. If I was in charge I would use WireGuard.
