Cisco Pix 515E outside NAT not working.

[kusok]

Hello

I am trying to configure VPN from a cisco pix 515E and all vpn clients connecting from outside interface cannot access any resources. The only thing they can do is ping the cisco pix itself.
I think I am forgetting something very simple as I have looked at a few dozen manuals and I cannot seem to figure this out. If anyone could help this would be great.

Here is the config I am using:

you have a lot of different stuff happening with this config. i'm going to suggets the following:
1) get rid of most of your NAT configuration statements:

no global (outside) 1 46.22.209.3-46.22.209.6 netmask 255.255.255.248
global (outside) 1 interface
no nat (outside) 0 access-list outbound
no nat (outside) 2 10.198.253.0 255.255.255.0 outside 0 0
no nat (inside) 0 access-list outbound
nat (inside) 1 0.0.0.0 0.0.0.0 0 0

2) your ip pool should be in a different network than what you have running on any interface:

no ip local pool mypool 10.198.253.3-10.198.253.254
ip local pool mypool 10.198.254.1-10.198.254.254

3) your outside ACL is incorrect:

no access-list outside
access-list nonat extended permit 10.198.253.0 0.0.0.255 10.198.254.0 0.0.0.255

nat (inside) 0 access-list nonat

try applying these three changes and post back with results.

I hate all Uppercase... I don't want my groups to seem angry at me all the time! =)

Thanks for your reply. Unfortunately my pix does not allow extended ACLs. Basically this is what it allows

Usage: [no] access-list compiled
[no] access-list deny-flow-max <n>
[no] access-list alert-interval <secs>
[no] access-list <id> compiled
[no] access-list <id> [line <line-num>] remark <text>
[no] access-list <id> [line <line-num>] deny|permit
<protocol>|object-group <protocol_obj_grp_id>
<sip> <smask> | interface <if_name> | object-group <network_obj_grp_id>
[<operator> <port> [<port>] | object-group <service_obj_grp_id>]
<dip> <dmask> | interface <if_name> | object-group <network_obj_grp_id>
[<operator> <port> [<port>] | object-group <service_obj_grp_id>]
[log [disable|default] | [<level>] [interval <secs>]]
[no] access-list <id> [line <line-num>] deny|permit icmp
<sip> <smask> | interface <if_name> | object-group <network_obj_grp_id>
<dip> <dmask> | interface <if_name> | object-group <network_obj_grp_id>
[<icmp_type> | object-group <icmp_type_obj_grp_id>]
[log [disable|default] | [<level>] [interval <secs>]]
Restricted ACLs for route-map use:
[no] access-list <id> deny|permit {any | <prefix> <mask> | host <address>}


What would be an easy way to allow everything with these options?

 

[kusok]

Alright, so I applied a non-extended acl like so:

access-list 101 permit ip 10.198.253.0 255.255.255.0 10.198.254.0 255.255.255.0

nat (inside) 0 access-list 101
nat (inside) 1 0.0.0.0 0.0.0.0 0 0


Unfortunately, the result is the same. I can ping only the pix itself from the vpn client, but nothing else.

 

[unclerico]

can you re-post your config with the changes intact?
