Hello,
I'm trying to move all my WG communication with peers to a non-primary
IP of my server.
It has IPs added like this:
inet6 2001:db8::ca6c/128 scope global deprecated
valid_lft forever preferred_lft 0sec
inet6 2001:db8::1/128 scope global nodad
valid_lft forever preferred_lft forever
What I tried:
ip6tables -t nat -I POSTROUTING -d 2000::/3 -p udp --dport 51820 -j
SNAT --to-source 2001:db8::ca6c
Also tried to filter by --sport, and also briefly without a port filter
at all.
This has zero effect, as shown by tcpdump all the WG traffic still
originates from 2001:db8::1
Does anyone have an idea why is that? Thanks
Did you try filtering based on fwmark ?
CONFIGURATION FILE FORMAT
The configuration file format is based on INI. There are two
top level sections -- Interface and Peer. Multiple Peer sections may be
specified, but only one Interface section may be specified.
The Interface section may contain the following fields:
• PrivateKey — a base64 private key generated by wg
genkey. Required.
• ListenPort — a 16-bit port for listening. Optional; if
not specified, chosen randomly.
• FwMark — a 32-bit fwmark for outgoing packets. If set
to 0 or "off", this option is disabled. May be specified in hexadecimal
by prepending "0x". Optional.
