Since my company has s Nortel VPN server, I took this binary and setup a conf file but I keep getting the error "vpnc: response was invalid [1]: (ISAKMP_N_INVALID_EXCHANGE_TYPE)(7)" Does anybody know what the issue is? I think I have all the necessary parameters, although we are using a SecureID token, and I've been entering the password as PIN+Token, and I always have this error. It that how it's supposed to work? My config file: IPSec gateway <server IP address> IPSec ID <ID given by my IT> IPSec secret <Group pwd given by my IT> Xauth username <my username> Xauth password <PIN+Token> vendor nortel Thanks, Vince.
