Description
Describe the bug
openwrt multiple interface can only visit one of it, It could be a problem with UDP binding.
Describe the environment
rustdesk-server 1.1.6-2
OpenWrt 22.03
How to Reproduce the bug
I have an OpenWrt router, there are 3 public network interfaces pppoe0, pppoe1, pppoe2, through nftables to input and output from an interface to a certain interface, but hbbs seems to be bound to the interface pppoe0 corresponding to the default route, from the public network can only access pppoe0, and access pppoe1, pppoe2 does not work, through wireshark packet capture to find hbbs 21116 UDP returns always use the address of pppoe0, and then I change the output address to pppoe1 or pppoe2 through the nftables' nat, which still doesn't work, while other applications such as openvpn can access pppoe1 and pppoe2 in this way.

Research direction
Start at hbbs's UDP binding and network handling, then reproduce with OpenWrt 22.03 and the three public interfaces pppoe0, pppoe1, and pppoe2. Done means clients can access hbbs through pppoe1 and pppoe2 as well as pppoe0, with UDP replies using the corresponding interface address.
