Pinggy provides the capability of IP whitelisting, allowing access restrictions based on specified IP addresses or ranges. This feature permits connections solely from designated IP addresses while disregarding requests from other addresses without any response.
Start tunnel with IP Whitelisting as follows
ssh -p 443 -R0:localhost:<localport> -t tlstcp@a.pinggy.io w:IP1
ssh -p 443 -R0:localhost:<localport> -t <token>+tlstcp@a.pinggy.io w:IP1
Like basic authentication, one can set multiple ip addresses as well.
ssh -p 443 -R0:localhost:<localport> -t tlstcp@a.pinggy.io w:[IP1[,IP2[,IP3..]]]
ssh -p 443 -R0:localhost:<localport> -t <token>+tlstcp@a.pinggy.io w:[IP1[,IP2[,IP3..]]]
