VPN Debugging Issues - "TOPO_SRV_ENABLED" and "VPN Acceleration Disabled Due to PPPoE Interface"

[SubZer0]

While debugging VPN on a FW, I found the following errors in the logs:

• vpn_cmain: Couldn't find TOPO_SRV_ENABLED in registry, setting it to 1
• VIF_HandlePPP: disabling VPN acceleration due to PPPoE interface

I followed the instructions provided by the vendor (SK articles sk151114 and sk92590), but was unsuccessful in resolving the issue.

This issue is occurring on an Appliance 3000 running R81.20 Jumbo Hotfix Take 76 whit MPLS and PPPoE interfaces.

Has anyone encountered similar issues or can offer any additional troubleshooting steps?

For TOPO_SRV_ENABLED, recommend to disable it with: https://support.checkpoint.com/results/sk/sk132712 
PPPoE disabling acceleration is expected behavior: https://support.checkpoint.com/results/sk/sk32578
