I'm pretty sure that's because you have an SNAT rule in your iptables (or an snat rule in your nftables) that sets the source IP to 164.X.X.X for traffics from 10.114.0.0/20 (or, all traffics, so to speak).

Solutions would be:

  1. adding ! -o lo to the rule, or
  2. adding -o eth0 to the rule (assuming the interface name is "static")
