One way only traffic is generally the result of one peer not having correctly established a security association. If there is any additional information regarding two other frequent problems РІР‚вЂњ one way only traffic and tunnel disconnections? VPN tunnel utility 'vpn tu' to remove SA keys from the table. If all of this works without any errors, then you may have previously initiated an invalid tunnel previously. Packet 2 from the responder agrees to its own subnet or host ID, encryption and hash algorithm.

Under the second ID field you should be able to see the peers VPN Domain configuration. VPN Domain configuration including the type (ID_IPV4_ADDR_SUBNET) and data (ID Data field).

> ID You should be able to see the initiators

You should be able to see the SA life Type, Duration, Authentication Alg, If your encryption fails here, it is one of the above Phase II settings that needs to be looked at. > tran1 ESP_AES (for an AES encrypted tunnel) In IkeView under the IP address of the peer, expand > 'P2 Quick Mode =>' for outgoing or 'P2 Quick Mode QM Packet 1 The DH key is combined with the key material to produce the symmetrical IPSec key. Peers exchange key material and agree encryption and integrity methods for IPSec. Phase II failures are generally due to a misconfigured VPN domain.Р”РЋ. IPSec Security Associations (SAs) are negotiated, the shared secret key material used for the SA is determined and there is an additional DH exchange. If your encryption fails in Main Mode Packet 5, then you need to check the authentication - Certificates or pre-shared secrets P acket 6 shows that the peer has agreed to the proposal and has authorised the host initiating the key exchange. The peers IP address shows in the ID field under MM packet 5. Packets 5 and 6 perform the authentication between the peers. The NONCE is a set of never before used random numbers sent to the other part, signed and returned to prove the parties identity. They perform key exchanges and include a large number called a NONCE. Packet 2 ( MM Packet 2 in the trace ) is from the responder to agree on one encryption and hash algorithm Packets 3 and 4 arent usually used when troublshooting. Proposed Encryption Algorithm, Key Length, Hash Algorithm, Authentication Method, DH Group, and SA renegotiation params (life type - usually secs and duration).Р”В®ncryption fails in Main Mode Packet 1, then you need to check your VPN communities. In IkeView under the IP address of the peer, open > 'P1 Main Mode =>' for outgoing or 'P1 Main Mode MM Packet 1 Each side generates a symmetric key (based upon the DH key and key material exchanged ). The peers exchange DH Key material (random bits and mathematical data) and methods for PhaseII are agreed for encryption and integrity. Each peer generates a shared secret from its private key and its peers public key, this is the DH key. Each peer generates a private Diffie-Hellman key from random bits and from that derives a DH public key. Peers Authenticate using Certificates or a pre-shared secret. Negotiates encryption methods (DES/3DES/AES etc), the key length, the hash Algorithm (MD5/SHA1) and creates a key to protect the messages of the exchange. Note that another useful tool is 'vpn debug on mon' which writes all of the IKE captured data into a file ikemonitor.snoop which you can open with wireshark or ethereal. IKEView.exe which parses the information of ike.elg into a GUI making this easier to view. To enable debugging, you need to login to your firewall and enter the command 'vpn debug on The $FWDIR/log/ike.elg file contains this information ( once IKE negotiation consists of two phases - Phase I (Main mode which is six packets) and Phase II (Quick Mode which is three packets).
