Opening Ports for Cisco VPN client from behind ASA 5505
I have been unable to run applications over a vpn connection since I installed an ASA 5505. I have tried adding the crypto isakmp nat-traversal 20 to the CLI but still am not able to run my applications. I do see "translation creation failed for protocol 50 src inside" errors being logged. I have recently spoken with the network admin at the location that hosts the applications and he told me that I need to open the following ports.
TCP : 10000
UDP: 4500
UDP: 500
ESP Traffic
Can someone post the CLI or directions to do this using ASDM? I am new to Cisco firewalls so bear with me. Also, what is he refering to when he says, "ESP Traffic"?

Here is my current running config. I have not had them check the vpn connection yet, I was hoping you could verify my config first. Thanks for your help I very much appriciate it.

I noticed that you are running
ASA Version 7.2(4) ASA Version 7.2(4)
I'd strongly recommend updating that to 8.0(3) or later.
Config looks good, give it a go.

They still are not able to open the programs. The connection is made but the applications that she needs to runn will not run. I see the following error in the log files of the ASA.

I dont know if this adds anything to the problem but since I replaced their Linksys router\firewall with the ASA I kept the linksys as an access point for wireless connections. She is currently connected wirelessly to they network.
If you are using the Linksys as a wirelss AP, have oyu disabled all of its routing/firewall functions? Your network should be plugged into the "inside" interfaces of the linksys, and not it's WAN port. If she is double NATting through the linksys and the ASA that will break VPN.
Based on your config, it looks like it ought to work. Hate to say it again, but this may be a caveat in the older version software. Adding to that the known published security vulnerabilities in the older software, and hte painless nature of hte upgrade, I'd say do it off hours, and then resume the troubleshooting.

Thanks for the thoughts. I will try upgrading the firmeware and let you know what I find out.
Double check that the port on your linksys is not in the WAN port. Or have your user try from a wired port with her wireless disabled. Two NICs active makes VPN clients malfunction as well.
guys sorry for hopping on this one, but I'm having a similar issue, and adding only ESP didn't take care of it. Would someone mind giving me the commands to add the VPNPortsTCP and VpnPortsUpd...
I'm assuming it will look like this:
access-list outside_access_in extended permit object-group VpnPortsTcp any any
access-list outside_access_in extended permit object-gropu VpnPortsUdp any any
correct?

ASKER CERTIFIED SOLUTION

This solution is only available to members.
To access this solution, you must be a member of Experts Exchange.
Assuming your outside ACL is called
access-list OUTSIDE-INBOUND
and your access group statement then was
access-group OUTSIDE-INBOUND in interface outside
then make avfew object groups like this:
object-group service VpnPortsTcp tcp
port-object eq 10000
object-group service VpnPortsUdp udp
port-object eq 4500
port-object eq 500
object-group protocol VpnProtocols
protocol-object 50
(some of these ports will translate to names once they are in, dont worry)
Then first try like this, ill assume to anyone?
access-list OUTSIDE-INBOUND extended permit object-group VpnProtocols any any
Then test it. Since udp & tcp should allow return traffic automagically unless you have an access list entry to deny it specifically, this will allow ESP traffic back into anyone. If that fails, post back your error log entries and we'll take the next step. (i know we didnt use the two tcp & udp service groups yet, its for later just in case, they arent "active" unless we use them in an ACL)
