firewalld and pptp - How to allow tcp traffic? (icmp traffic works)


Good afternoon!

I have a Fedora Core 24 server running firewalld and pptpd. When a client VPN connects, the client can ping internal LAN IP addresses but cannot connect using ssh, etc.

I have confirmed that my firewalld configuration is the issue as when it is turned off all traffic flows as expected. When firewalld is on, only icmp traffic (pings) flow through the VPN.

What is the proper way to configure firewalld to allow all traffic coming in through the VPN tunnel (ppp0) to have access to all ports and services available in the LAN?

I solved the issue. My external interface was on the "external" zone, my internal interface was on the "internal" zone and I had attempted to add the ppp0 interface to one or the other and add port 22 access by IP.

It turns out that all I needed to do was add the ppp+ interface to the "trusted" zone and all is well.

I hope this helps someone else out there.
