Originally created by @ndziuba on GitHub (Jul 30, 2024).

When creating a DNS Network Route masquerading is set by default.
This results in the following rule for routing nodes when running: iptables -t nat -S
-A NETBIRD-RT-NAT -j MASQUERADE
-A NETBIRD-RT-NAT -j MASQUERADE

Because of that every traffic trough a routing node that has this route gets masqueraded as no -s or -d flags are set.
Even when masquerading is deactivated for another route.

Deactivating masq for the DNS route fixes this behaviour.
But that means they cant be used with masquerading on a node that has non-masqueraded routes.

NetBird version

0.28.6
