I wonder there are way to read .backup and edit?
but I do this method seem fixed it.
- I dump into .rsc file
- factory reset
- use quick set (defconf remain)
- configure basic stuff like IPv6, Cloud, DoH, disable fasttrack (need use queue), etc
- test speed, 2G/1G as expected
- reboot
- test speed, 2G/1G as expected
- backup (just in case)
now edit .rsc file, remove what already exist (sanitize), re arrange line who take precedence, for example: add address list first before add filter/nat that use address list.
hard part like Wireguard, BGP, Routing, Port Forward, etc will be restore via SSH (paste all line)
then I reboot
verify all SD-WAN IPIP/IPIPv6 tunnel works, BGP, Route etc…
Then do speedtest again, this time, no weird speed drop, achieve 2Gbps download and 1Gbps upload on both IPv4/6 with Queue Tree active and fasttrack disabled:
This make me wonder, what inside of .backup file? Contain hidden internal states?
