How to add UDP port to main table for DNS queries?

[engageub]

Hi,

I am redirecting UDP traffic based on ip address by adding them to main look up table.
Is it possible to add all ip address based on udp port or ignore udp traffic from tun0 adapter and send it to direct connection.
This is important to resolve DNS queries.

tun2socks/docker/entrypoint.sh

Line 45 in d061f1c

for addr in $(echo "$TUN_EXCLUDED_ROUTES" | tr ',' '\n'); do

Adding the dns ips using the following works. How to add udp port?
ip rule add to "$addr" table main

Thank you
