Re: Unable to access remote side router via IPSec
For testing, try:
# config vpn ipsec phase1-interface
# edit phase-1-name
# set npu-offload disable
I've come across this issue with 6.0.4 and haven't found a solution. Also testing with iperf showed there was a performance impact with it enabled. Unfortunately, it means the encryption will be handled by the CPU which could also have a performance impact, depending on the amount of traffic going through the firewall.
