L2TP Problem with CISCO
Good morning everyone.
Today i've tried to set up an L2TP Tunnel between my Pfsense and a foreign CISCO Router. Note: Only L2TP without IPSec!
I've created the L2TP Server as described at the Pfsense doc's section. (Set an IP Adress, unused by Firewall, added a remote Client subnet, pasted my secret Password, authentication type PAP and let everything else unchanged)
Then i created the Firewallrules (L2TP Tab allow any to any on all Ports; wan tab allow 1701 UDP from any)
Now i can see the CISCO Box connecting, but i get immediatly the following:
Jun 2 14:16:26 l2tps: L2TP: Control connection 0x803462308 destroyed
Jun 2 14:16:15 l2tps: L2TP: Control connection 0x803462308 terminated: 0 ()
Jun 2 14:16:15 l2tps: Incoming L2TP packet from 18.104.22.168 1701
My tcpdump on the WAN Interface looks like this:
IP 22.214.171.124.1701 > 126.96.36.199.1701: l2tp:TLSNs=0,Nr=1 *MSGTYPE(StopCCN) *ASSND_TUN_ID(61512) *RESULT_CODE(4/0)
14:21:22.026952 IP 188.8.131.52.1701 > 184.108.40.206.1701: l2tp:TLSNs=1,Nr=1 ZLB
14:22:37.009611 IP 220.127.116.11.1701 > 18.104.22.168.1701: l2tp:TLSNs=0,Nr=0 *MSGTYPE(SCCRQ) *PROTO_VER(1.0) FIRM_VER(4400) *HOST_NAME(vcdsl2) VENDOR_NAME(Cisco Systems, Inc.) *RECV_WIN_SIZE(20050) *CHALLENGE(fhuezfgg62g83e34d3e0162) *ASSND_TUN_ID(65256) *FRAMING_CAP() *BEARER_CAP() VENDOR0009:ATTR006e()
Of course i changed the IP Adresses and the challenge request.
Could someone point me to the right direction please? I think i am missing something, but dunno what.
Thanks in advance
I'm still trying to get this things working….
