PIX 506 to Linksys BEFVPN41 VPN connection issue

I am trying to set up a VPN between a Cisco PIX 506 w/ IOS 6.3(5) and a Linksys BEFVPN41. Below is the config from the PIX and the resulting log from the Linksys. I am using the Linksys BEFVPN as I believe this is supposed to be operable with a PIX. I saw from many threads that Linksys BEFSX41s are problematic to say the least with a PIX.

Here is the config on my Cisco PIX:

ip address outside

ip address inside

sysopt connection permit-ipsec

sysopt connection permit-pptp

crypto ipsec transform-set ESP-3DES-MD5 esp-3des esp-md5-hmac

crypto ipsec transform-set ESP-DES-MD5 esp-des esp-md5-hmac

crypto ipsec transform-set ESP-DES-SHA esp-des esp-sha-hmac

vpdn group PPTP-VPDN-GROUP pptp echo 60

vpdn group PPTP-VPDN-GROUP client authentication local

Here is the log output on the Linksys BEFVPN41:

2005-10-10 22:01:07 IKE[1] Tx >> QM_I1 : HASH, SA, NONCE, ID, ID

One problem is I have changed the config on both so many times I believe somewhere I might have screwed up. I have re-read the Cisco config over and over and can not seem to see what I might have done wrong. Any ideas? Also, in past we found we could not use a PPTP and Cisco dial in VPN as they would conflict with each other. But as far as I know a PPTP should not conflict with this IPsec tunnel correct?


Re: PIX 506 to Linksys BEFVPN41 VPN connection issue

Your configs on the PIX looks good to me. I would suggest you to verify if the policies match at both ends of the tunnel. Also, as per my understanding, configuring PPTP and dial-in VPDN must not conflict, because they use different ports.
