Configuring Remote Access VPN on ASA 5510

[RMurr34]

Good afternoon,

I'm looking for some assistance with configuring remote access VPN on an ASA 5510. I have good experience with a VPN concentrator using the GUI but not an ASA using the CLI.

I have a remote location where I recently moved some corporate servers and people need to VPN into that location to carry-out certain tasks. We use the Cisco version 4.8 and 5 VPN client.

Any assistance provided will be greatly appreciated.

Here's my current ASA config:

I played around with the configs and I was able to get to the point where
I can actually VPN into my site.

However, that's all I can do. I can't ping or RDP to anything.

Your VPN pool should not be part of your internal network.

ip local pool vpnpool 192.168.60.100-192.168.60.130

Change it to a different subnet and be sure to give it the nat exemption. You also need to add your group policy. Take a look at this and compare with your config -

What is all this stuff for??? You don't have any routes to these networks internal or dmz.
static (inside,dmz) 192.168.10.0 192.168.10.0 netmask 255.255.255.0
static (inside,dmz) 192.168.20.0 192.168.20.0 netmask 255.255.255.0
static (inside,dmz) 192.168.30.0 192.168.30.0 netmask 255.255.255.0
static (inside,dmz) 192.168.40.0 192.168.40.0 netmask 255.255.255.0
static (inside,dmz) 192.168.50.0 192.168.50.0 netmask 255.255.255.0
static (inside,dmz) 192.168.60.0 192.168.60.0 netmask 255.255.255.0

You don't need this - you allow everything anyway -
access-group inside_access_in in interface inside

Hi Brent,

First of all, thanks for your help. I grealy appreciate the outstanding help I continue to receive on these boards.

Regarding your comment about my VPN pool should not be a part of my internal network. I used the pool I did because looking at the link you sent me (which I used to configure my device) they appeared to use it in their example.

interface Ethernet0/1
nameif inside
security-level 100
ip address 172.16.1.2 255.255.255.0

ip local pool vpnpool 172.16.1.100-172.16.1.199 mask 255.255.255.0

Should I use something like 10.10.10.100-10.10.10.130?

I will remove those static entries for (inside,dmz). Thanks for pointing that out.

I was on the phone earlier with a Cisco tech and he helped me get VPN up. He did mention something about my vpn pool as well.

However, I'm able to VPN and then RDP but I have to use the server IP addresses because the server name will not work.

I would also like to set authentication up by using our Active Directory user accounts rather than a group user. The Cisco tech told me to run these commands but it doesn't seem to have any effect:

aaa-server vpn protocol radius
aaa-server vpn host (IP of my domain controller)
key xxxxxx

One question on the key. What does that handshake with? I'm confused on what it's authenticating with.

Thanks for your help.
