Having problem getting my VPN setup correctly on my Pix 501.
I can connect with the Cisco VPN Client but cannot access any of the servers on the internal network. (I'm trying this from the inside interface first.) See below for config.

Re: Need Help - First Time VPN Setup On Pix 501 9 years 7 months ago #20897

you have to allow your ip local pool to access your network via an access list.

Your local pool:

ip local pool ipvpn 10.0.0.20-10.0.0.29 mask 255.255.255.0

Example access-list which will give that pool access to your network:

access-list NoNAT permit ip 10.0.0.0 255.255.255.0 10.0.0.20 255.255.255.240

Then if you didn't want those connections to be NAT'd then you could add:

nat (inside) 0 access-list NoNAT
The administrator has disabled public write access.

Still Have Same Problem. Can't access internal network. 9 years 7 months ago #20976

Please look at above configuration. Made changes but still no luck accessing internal network. Any help is appreciated.

Apply the following commands:

no crypto dynamic-map inside_dyn_map 20 set transform-set ESP-3DES-MD5
no crypto dynamic-map outside_dyn_map 20 match address outside_cryptomap_dyn_20
no access-list inside_outbound_nat0_acl permit ip any 10.0.1.0 255.255.255.224
no isakmp enable inside
isakmp identity address
crypto isakmp nat-t 20
access-list inside_outbound_nat0_acl permit ip 10.0.0.0 255.255.255.0 10.0.1.0 255.255.255.224
access-list splitTunnelAcl permit ip 10.0.0.0 255.255.255.0 10.0.1.0 255.255.255.224
vpngroup vpnext split-tunnel splitTunnelAcl

Try to avoid PDM for the configuration. Use CLI prompt..
