Not able to telnet smtp server from google cloud vm
Question
We have a account on mailGun .
we can ping and telnet to smtp.mailgun.org port 25 from our local system.
But when we use google cloud vm then
ping smtp.mailgun.org is successfull, But telnet smtp.mailgun.org 25 stucks at trying...
current firewall rules has 0.0.0.0/0 tcp:1-60000 entry in it. Iptables are off. OS: RHEL7
