Disable setting DNS for a forticlient portal

[aseques]

We are using tunnel mode VPNs on our firewall. Now there's a subset of users that need to use another vpn client from another vendor as their main VPN while retaining our VPN client for som other uses.

I tried setting the dns-server1 / dns-server2 inside "config vpn ssl web portal" but it doesn't seem to have any effect because the VPNs still have the default dns pushed (not the ones set by me)

The desired effect would be to disable setting the DNS entirely in this case (but intermediate solutions might work)

Reading through the documentation I've found this (https://community.fortinet.com/t5/FortiGate/Technical-Tip-Configuring-DNS-servers-per-SSL-VPN-Portal...Specifying the DNS server settings at the portal level is overriding those at the global level." and it doesn't seem to work in my case (it's because I'm using tunnel mode??)

Any ideas?

Hello aseques,

Could you please indicate under which version your units are running?

I will then check if there is another documentation.

Hello aseques,

Meanwhile I am asking some support, could you please check this document?:

https://docs.fortinet.com/document/fortigate/6.2.0/cookbook/960561/fortigate-dns-server

Hi @Anthony_E  I read through that page, it's related to the DNS system for fortigate, I'm interested on the DNS sent to de VPN client, that isn't covered on that page.

Thanks
