Hi,

This command:
static (outside,inside) 64.168.82.251 192.168.1.2 netmask 255.255.255.255
Should look like this:
static (inside,outside) 64.168.82.251 192.168.1.2 netmask 255.255.255.255

That should take care of the web server.

For the VPN client:
Enable the command:
management-access inside

And post the output from:
sh cry isa sa
sh cry ips sa

When attempting to connect from the VPN client.

Federico.

[sivapkd100]

Webserver - : I have changed the static to (inside, outside), still it did not work, any more help will be really appreciated.

VPN: --   Here is the output

ciscoasa(config)# sh cry isa sa

There are no isakmp sas
ciscoasa(config)# sh cry ips sa

There are no ipsec sas

I have observed the log while connecting the VPN and it show some mismatching. Here is below.

Removing peer from correlator table failed, no match!

Re: Webserver  is not able to access from outside the network, VPN in not accepting

[Federico Coto Fajardo]

Check with the command:
sh access-list inside_access_in
that port 80 traffic is getting hitted to the ACL from the outside.
This is because if I do a ''telnet 64.168.82.251 80'' the traffic seems to hit the server.

Question:
Can you reach the webserver from inside the ASA?

Regarding the VPN:
Phase 2 is not matching.
Please post the output from:
debug cry ipse 127

Federico.

[sivapkd100]

Thanks for your reply.

I just reconfigured the VPN part and client is able to connect the VPN successfully. But two problmes still facing.

VPN client is not able to ping or access any resources from INISIDE the network. VPN disconnects after 30 minutes.

I am still working on the webserver access from aoutside part.

Any help will be highly appreciated.

Thanks

Siva

[Jennifer Halim]

Hi Siva,

Just tested to browse: http://64.168.82.251, and it works OK (it's the Apache 2 Test Page). Seems like the webserver is now up and working.

For the VPN access, to ping the internal subnet after you are connected, please add the following:

crypto isakmp nat-traversal 25

policy-map global_policy
  class inspection_default
       inspect icmp

Also, can you ping 192.168.1.1 after connected via VPN?

Hope that helps.

[sivapkd100]

Good Morning.

Yes, I fixed the webserver access from outside yesterday. It was the NAT issue and below lines added (it might help someone too, so I am pasting).

Static nat for webserver

static (inside,outside) 64.168.82.251 192.168.1.50 netmask 255.255.255.255
access-list outside_access_in permit tcp any host 64.168.82.251  80
access-group outside_access_in in interface outside

---------------------------------------------------------------------------------------

For VPN , I am  connecting from home, receiving the IP from VPN-POOL (10.10.100.2) and I can ping locally. But not any other IP address such as

192.168.1.1, 4.2.2.2.    Even local internet won't work if I connect VPN.

any thoughts?

Thanks,

[Federico Coto Fajardo]

Glad for the webserver.

For the VPN, check if by adding the commands:

management-access inside

crypto isakmp nat-t

sysopt connection permit-vpn

Can you PING 192.168.1.1 now?

Make sure that anything else that you want to reach has a default gateway pointing to the ASA.

Federico.

[sivapkd100]

I have added the commands.  VPN connecting and receiving the IP address from the Pool.  Still cant ping the inside hosts.  Please Help......

[Federico Coto Fajardo · Accepted solution]

You still have not answered me if from the VPN clients you can PING 192.168.1.1?

And if 192.168.1.1 is the deafult gateway for the local LAN behind the ASA?

Federico.

[sivapkd100]

sorry for the late reply.

I could not ping 192.168.1.1 or any IP. But VPN is connecting successfully. ANother thing I had noticed is after connecting VPN I could not browse locally Also.

Please see my current configuration attached in txt file.

[Federico Coto Fajardo · Accepted solution]

Siva,

The reason you're not able to access the inside network from the VPN clients, is because your NAT 0 statement looks like this:

access-list inside_nat0_outbound extended permit ip 192.168.100.0 255.255.255.0
192.168.100.0 255.255.255.128

Should look like this:

access-list inside_nat0_outbound extended permit ip 192.168.1.0 255.255.255.0
192.168.100.0 255.255.255.128

Also, the reason that you lose Internet when connecting with VPN is because there's no split-tunneling configured:

access-list split-tunneling extended permit ip 192.168.100.0 255.255.255.0
192.168.100.0 255.255.255.128

group-policy ciscovpn attributes

      split-tunnel-policy tunnelspecified
      split-tunnel-network-list value split-tunneling

tunnel-group ciscovpn general-attributes

     default-group-policy ciscovpn

Add this commands on the ASA and see if you can PING:

sysopt connection permit-vpn   --> this might not take it

crypto isakmp nat-t

Disconnect the VPN client, and connect and try again.
