Wrong DNS address in TUN mode

Operating system

Version

Description

In TUN mode the system DNS address is set by Throne to 172.19.0.2 (the default). But this DNS server doesn't respond. The 172.19.0.1 responds fine. Because of that, DNS doesn't work on my system in TUN mode, unless I set the DNS server to 172.19.0.1 in system settings.

Throne seems to set DNS address to whatever is set in Tun settings "IPv4 CIDR" + 1.

Another thing, could be unrelated: in the logs i see
link icmp connection from 172.19.0.1 to 1.1.1.1: icmp is not supported by default outbound: proxy

Reproduction

Tun settings
IPv4 CIDR: 172.19.0.1/24 and Enable Tun Routing: ON (other checkboxes are off)

Tun mode: ON
Stack: system, gvisor, mixed - all work the same.
