Allow multiple peers, tunnels, and proxies

jordemort commented 1 year ago

Allow multiple peers; peer specific-stuff is broken out into a new PeerConfig struct, which DeviceConfig now contains an array of
Support the AllowedIPs configuration option on peers; if unspecified, defaults to allowing everything as before
Allow multiple tunnels & proxies by setting AllowNonUniqueSections: true on the INI parser

Tested with multiple peers, tunnels, and allowed IPs in my home network

Would you happen to have an example config for testing out multiple peers / tunnels?

Sure, here's a heavily redacted version of what I'm running:

[Interface]
Address = 10.254.254.40/32
PrivateKey = XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX=

[Peer]
Endpoint = 192.168.0.204:51820
PublicKey = YYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYYY=
AllowedIPs = 10.254.254.100/32
PersistentKeepalive = 25

[Peer]
PublicKey = ZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZ=
AllowedIPs = 10.254.254.1/32, fdee:1337:c000:d00d::1/128
Endpoint = 172.16.0.185:44044
PersistentKeepalive = 25

[TCPServerTunnel]
ListenPort = 5000
Target = service-one.servicenet:5000

[TCPServerTunnel]
ListenPort = 5001
Target = service-two.servicenet:5001

[TCPServerTunnel]
ListenPort = 5080
Target = service-three.servicenet:80

I've got a big server at home and a smallish VPS in the cloud. I want to expose some, but not all, of the services that I have on my big server to my VPS. With wireproxy, I can pick off specific ports and forward them to the VPS without putting my whole big server on the same VPN as it and potentially exposing more than I intended.

In the example config, the services on 10.254.254.40 are accessible to both peers at .1 and .100
