File transfers failing across S2S VPN after Cisco ASA firmware upgrade.
I recently upgraded our Cisco ASA 5545 to version 9.9(2)36. Since the upgrade we are not able to transfer files to/from our Azure tenants via the site to site vpn we have setup. Here is an example: vpn, tunnel
Local Server: 10.1.1.151 Azure server: 10.211.20.100
We can ping both ways fine, but file trans are failing. It just hangs when I try a transfer. For the monitoring I am seeing TCP Reset-I from inside. Could this be the reason the file transfers are failing? If so, anybody have any idea how to remedy that reset??
