Telnet to port 80 on a remote network not going through

[PTirop]

Hello,

I have a branch network x.x.x.x connected via VPN to HQ y.y.y.y. Telnet to port 80 on a server on the branch network from HQ is failing. The port is open on the server and the branch can access it. However HQ cannot. Please assist.

Might this be an MTU issue?

It shouldn't be an MTU issue if you're simply doing a telnet session.

It sounds more likely that a firewall rule in the site-to-site firewall settings would be blocking it.

Either that, or you have a routing problem.

Can you perform a capture on the server to see if it receives any packets from the source when you initiate the telnet?

This is I am accessing a service on http.

I actually have no site-t0-site firewall rule set.

I cannot seem to see any hits on the server.

To a packet capture from the Meraki dashboard at both the branch and the server, and trace it through to you find the point it fails.

Can you ping the server?  Does the server have a default gateway pointing to the MX?  Is the subnet mask right on the server?
