We are facing a problem exchanging information in HL7 protocol in a standard environment listener\receiver.
Our application works fine on a plain network, get some errors on an ipsec vpn tunnel.
I'm not an expert, seems to be a problem related to packet fragmentation, any packets are truncated and cannot be managed.
this no happens on the same lan, so we are pointing to MTU or SECURITY CONTROL applied on vpn.
Can you help me ?
Sorry , i'm not providing many details, please ask me what you think is important..
