Site2Site IPSEC VPN unable to ping remote subnet

  • Hi All,

    We have establish a Site2Site IPSEC VPN between Cisco 857 router and PFSense 2.0 box, unfortunately we're unable to ping from source to destination and visa versa…..I followed this tutorial "" and still no luck.

    We have a fully working Site2Site IPSEC VPN between 2 PFSense boxes, just an issue with Cisco 857 router to PFSense.

    Cisco config;

    crypto isakmp policy 10
    encr 3des
    authentication pre-share
    group 2 
    crypto isakmp key ABC123 address 203.XXX.XXX.XXX
    crypto ipsec transform-set 3DES-SHA esp-3des esp-sha-hmac
    crypto map PFSVPN 15 ipsec-isakmp
    set peer 203.XXX.XXX.XXX
    set transform-set 3DES-SHA
    set pfs group2
    match address 101
    access-list 101 permit ip
    access-list 101 permit ip
    interface Dialer0
    crypto map PFSVPN


  • @ferret:

    crypto isakmp key ABC123 address 203.XXX.XXX.XXX no-xauth

    that was the difference, when looked very fast preview
