Question:
I cannot adjust the Negotiation Mode on web GUI. How can I set the VPN Negotiation Mode to Aggressive on a USG FLEX H firewall?
Answer:
Currently, the Negotiation Mode does not have a GUI configuration option. You can set it using CLI instead. Assuming you have already added a site-to-site VPN named testvpn1 (IKEv1) via the GUI.
usgflex200h> edit running
usgflex200h running config# vrf main ike ike-policy-template testvpn1 aggressive true
usgflex200h running config# show config vrf main ike ike-policy-template testvp1
