I've followed the instructions to configure a VPN between a netscreen device and a Cisco PIX as directed by Cisco's [netscreen to PIX VPN]http://www.cisco.com/en/US/tech/tk583/tk372/technologies_configuration_example09186a00801c4445.shtml article. The only differences are that I'm running PIX 6.3(5) and Juniper Netscreen 6.1.0r2.0 (Firewall+VPN). I followed both configurations exactly, and when I try to connect, the Juniper returns with: 2010-02-21 12:54:28 information IKE: Removed Phase 2 SAs after receiving a notification message. 2010-02-21 12:54:28 information IKE pix_public_IP: Received a notification message for DOI 1 14 NO-PROPOSAL-CHOSEN. 2010-02-21 12:54:28 information IKE pix_public_IP Phase 2: Initiated negotiations. On the Netscreen, I've created a Phase 2 Proposal called ToCorpOffice using DH Group#2, 3DES-CBC, and SHA-1, and when configuring the AutoKey IKE, I chose ToCorpOffice and removed all other transforms. I believe I've configured the same on the PIX with: sysopt connection permit-ipsec crypto ipsec transform-set mytrans esp-3des esp-sha-hmac crypto map mymap 10 ipsec-isakmp crypto map mymap 10 match address nonat crypto map mymap 10 set pfs group2 crypto map mymap 10 set peer netscreen_public_ip crypto map mymap 10 set transform-set mytrans crypto map mymap interface outside Saved that and rebooted, so here's the cryptomap info: PIX-FW1# show crypto map Crypto Map: "mymap" interfaces: { outside } Crypto Map "mymap" 10 ipsec-isakmp Peer = netscreen_public_ip access-list nonat; 1 elements access-list nonat line 1 permit ip 192.168.1.0 255.255.255.0 192.168.2.0 255.255.255.0 (hitcnt=0) Current peer: netscreen_public_ip Security association lifetime: 4608000 kilobytes/28800 seconds PFS (Y/N): Y DH group: group2 Transform sets={ mytrans, } PIX-FW1# Any idea why I'm getting a NO-PROPOSAL-CHOSEN error?
