Hi Expert,

 

I need your support as I have configred Ipsec over SDWAN configuration between HQ to branch office.

phase 1 & phase 2 tunnels are showing up but performance SLA is showing down. I have put so many effort but no luck succeded. that's the reason I came here for help. Until perfomance SLA comes up I will not able to set traffic from HQ to Branch.

is 192.168.1.0/24 a local network in HQ ?

where should 192.168.2.0/24 be located? i would guess in branch.

 

are these networks permitted in the ipsec selectors and are routes correctly instaled in RIB for them, also firewall rules in place ?

the format you gave is kinda off, but i think you have routes towards them via Null ?
