DESCRIPTION: Traffic from the LAN side of a SonicWall NSA appliance bound for a VPN'd network behind a SonicWall TZ 190W is dropped at the NSA appliance with the following error: “SA not found on lookup by SPI for outbound pkt.”
SonicWall Global VPN Client connections cause S2S VPNs to begin dropping TCP sessions (e.g., RDP connections).
Occurs when there are multiple failovers on the SonicWall TZ190W from PPPoE WAN to WWAN and back.
Upgrading to SonicOS Enhanced 188.8.131.52 or above resolves the issue.
