I'm troubleshooting a connection between a client PC and an HTTP server. In this example, the client is requesting a file and only receives a few KB before the connection is reset. The server sends four packets, then the client ACKs the first packet only, which appears to trigger the server to retransmit the un-ACKed packets. After several retransmissions the connection times out. There is an IPsec tunnel between the client and the server. Any thoughts on this behaviour? Edits: There is a site-to-site IPsec tunnel between the client (192.168.120.105) and server (10.21.8.54). The captures were taken from the client (Win10). |
