client 1:
connecting from: 219.88.65.32
connecting to: 222.23.53.32
status: connected via PPTP VPN tunnelling

client 2:
connecting from: 222.23.53.32
connecting to: 219.88.65.32
status: trying to connect via PPTP VPN but is always failing ... "No response from host"

While client 1 is connected, client 2 is trying to connect to the site where client 1 is, and it is failing.  can PPTP handle both incoming connection outgoing connection between two sites at the same time?

sure can, the host port is different from the destination port.

No I don't believe it can. It can handle incoming and out going to different sites, but you are trying to create two tunnels between the same two sites. Even if they would connect there would be severe routing issues.

yes, that's true Rob, but routing is not a feature of pptp and pptp doesn't affect the functionality of routing.

But I agree, its erroneous to set it up this way.

Are You Ready for GDPR?

With the GDPR deadline set for May 25, 2018, many organizations are ill-prepared due to uncertainty about the criteria for compliance. According to a recent WatchGuard survey, a staggering 37% of respondents don't even know if their organization needs to comply with GDPR. Do you?

My assumption would be that both VPNs have a different gateway address but with the same remote subnet. Which route/VPN would the packets take?

With PPTP in mind, how does a site-to-site VPN work using PPTP?

Not sure I understand the question.
Generally a site-to-site tunnel is done these days with 2 VPN routers. VPN routers these days are so inexpensive (starting at $150) that the labor costs, lack of stability, and slightly reduced performance make site-to-site VPN's using servers almost obsolete. Configuring site-to-site with 2 servers is very time consuming. The routers would normally uses IPSec which is more secure but some can be configured to use PPTP.
