Hello, I have a new R7000 and I just installed DD-WRT v3.0-r30870M kongac. I can't get the vpnc client to connect to my company's Cisco router running 15.1(4)M. This is what I get:
configuration response rejected: (ISAKMP_N_ATTRIBUTES_NOT_SUPPORTED)(13)ifconfig: bad address ''
RTNETLINK answers: File exists
RTNETLINK answers: Network is down
RTNETLINK answers: Network is down
RTNETLINK answers: Network is down
RTNETLINK answers: Network is down
quick mode response rejected: (ISAKMP_N_INVALID_PAYLOAD_TYPE)(1)
this means the concentrator did not like what we had to offer.
Possible reasons are:
* concentrator configured to require a firewall
this locks out even Cisco clients on any platform expect windows
which is an obvious security improvment. There is no workaround (yet).
* concentrator configured to require IP compression
this is not yet supported by vpnc.
Note: the Cisco Concentrator Documentation recommends against using
compression, expect on low-bandwith (read: ISDN) links, because it
uses much CPU-resources on the concentrator
quick mode response rejected [2]: (ISAKMP_N_INVALID_PAYLOAD_TYPE)(1)Segmentation fault
My vpn.conf is simple:
IPSec gateway x.x.x.x
IPSec ID <grpname>
IPSec secret <unencrypted secret>
Xauth username <myusername>
Xauth password <unencrypted password>
Script /tmp/etc/vpnc/wrapper.sh
Can anyone help me to get this working. Thanks!
