network question

[Jeff Peng]

may I ask a network question?

when my server is a vps who has floating IP (that means, the server's iP
is an internal IP, the public ip is bond on provider's router/firewall
devices), then my ssh client connecting to the server will never
disconnect even if I changed my local gateway (for example switching
VPN).

if the vps is a normal IPv4 box then switching localnet will always
disconnect.

what's the reason?

thanks.

If you enable a VPN tunnel traffic may go through, but it is also
possible to bind it to a specific interface tat doesn't care about the
tunnel.
Use a network sniffer to investigate that.
