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.
