Hi
I have in my company Symantec Gateway Security 360R. I must connect external
office over vpn to sgs. In office I have Linksys router BEFVP41. How may I
correctly setup router BEFVP41 (or SGS 360R)?
In logs on SGS I have: "

end of log
VPN_test - Terminating connection
VPN_test - Sending ISAKMP OAK INFO (Notification IKE SA)
VPN_test - state transition function for STATE_QUICK_R0 failed.
NO_PROPOSAL_CHOSEN
VPN_test - (null): NO_PROPOSAL_CHOSEN
VPN_test - ERRno acceptable Proposal in IPSec SA
VPN_test - STATE_MAIN_R3 sent MR3, ISAKMP SA established
VPN_test - STATE_MAIN_R2: from STATE_MAIN_R1; sent MR2; expecting MI3
VPN_test - STATE_MAIN_R1: from STATE_MAIN_R0; sent MR1; expecting MI2
VPN_test - Responding to Main Mode from Remote Peer xxx.xxx.xxx.xxx
start of log

I have enabled IPSec Passthrough, PPPOE, PPPTP, MD5, SHA and disabled PFS.
And without success :-(

Has someone VPN Symantec 300'series - Linksys maybe?
