Question : Problem: Pix to Netscreen VPN
|
|
I am working on getting a PIX515 to connect to a Netscreen 5GT
In my lab I have a PIX 501 running 6.3(4). I can connect to my 5GT without any problems
When I do a get sa from the Netscreen I get
0000000a< 6*.*.*.* 500 esp:3des/md5 2695cc0c 28610 403M A/- -1 0 0000000a> 6*.*.*.* 500 esp:3des/md5 e614d74c 28610 403M A/- -1 0
When i try and connect to my 515 in production running 6.3(1) it wont connect and I get the following
0000000a< 6*.*.*.* 500 esp:3des/md5 00000000 expir unlim I/I -1 0 0000000a> 6*.*.*.* 500 esp:3des/md5 00000000 expir unlim I/I -1 0
Here is the error in the logs 2006-12-20 08:06:21 info IKE: Removed Phase 2 SAs after receiving a notification message. 2006-12-20 08:06:21 info IKE<*.*.*.*>: Received a notification message for DOI <1> <14> . 2006-12-20 08:06:21 info IKE<*.*.*.*> Phase 2: Initiated negotiations.
here are the relvant portions of the configs
set ike p1-proposal "toPIX" preshare group2 esp 3des md5 second 86400 set ike p2-proposal "toPIX" group2 esp 3des md5 second 3600 set vpn "VPN" gateway "GW" no-replay tunnel idletime 0 proposal "g2-esp-3des-md5" set vpn "VPN" id 10 bind interface tunnel.1 set vpn "VPN" proxy-id local-ip 172.16.10.0/24 remote-ip 172.16.0.0/24 "ANY"
Here is the config that isnt working
crypto ipsec transform-set caset esp-3des esp-md5-hmac crypto map newmap 20 ipsec-isakmp dynamic camap crypto map newmap 200 ipsec-isakmp crypto map newmap 200 match address 200 crypto map newmap 200 set peer *.*.*.* crypto map newmap 200 set transform-set caset crypto map newmap interface outside isakmp enable outside isakmp identity address isakmp policy 10 authentication pre-share isakmp policy 10 encryption 3des isakmp policy 10 hash md5 isakmp policy 10 group 2 isakmp policy 10 lifetime 86400

>my 515 in production running 6.3(1) Very buggy version of Pix code. Suggest updating to 6.3(5)
>crypto map newmap 20 ipsec-isakmp dynamic camap This is the difference between the set that works and the one that does not. The dynamic entry (20 here) should be higher than all the statics. Try: crypto map newmap 200 set peer *.*.*.* crypto map newmap 2000 ipsec-isakmp dynamic camap
