I have PIX 501 conected a modem where i configured a vpn, I created a vpngroup and I give all the permission, I can connect across the vpn but my problem is that I can't to ping the pix and inside network.
I used the command split tunneling and nonat for the VPN's ip.
Please do the following:
1) Try to enable NAT-T
2) Try to change your split-tunnel ACL from extended to standard.
