Recommended VPN Server configuration

[fbeye]

Hello

I was wondering what would be considered  the correct/ current VPN setup to use.

My situation is residential and I am simply wanting to use my iOS devices (iPhone/iPad) to access specific IP address on my LAN to read/write documents and multimedia via VPN.

I know iPhone / IPad has VPN Support but would prefer to use Cisco anyConnect client software. 

Was just looking for a direction to take in regards to which confirmation format and security to use so I know where to research.

thank you

Hi,
Is this just for personal use and looking for a cheap solution?

Personally i use a Cisco 1921 router with FlexVPN IKEv2/IPSec RA VPN solution, using a self signed certificate (could be either Cisco or Linux CA) with the AnyConnect VPN Client.

Alternatively you could acquire an ASA 5506-X and run either SSL-VPN or IKEv2/IPSec VPN with AnyConnect client.

I apologize it did not even occur to me to mention what I am utilizing currently. I have a 5508-X. Being that the 5506-X would be configured the same as my 5508 then I will use this... I am just uncertain as to procedure.
You mention SSL-VPN or IKEv2/IPSec VPN with AnyConnect so that will be my path to take.
Thank you

[Rob Ingram]

Ok. Here are some examples:- SSLVPN or IKEv2/IPSec

It's pretty straight forward to configure either. The examples use RADIUS for authentication but you can use a local account on the ASA or just certificate authentication, as long as the client device and ASA mutual trust the certificates used.

HTH

[fbeye]

Thank you so much. Tonight I will look into this and when I complete it or if I have more questions I’ll  let you know. 

[fbeye]

To verify my understanding, the 2 links you gave me are the authentication methods to use once I have already configured the server on the ASA?

[Rob Ingram]

Hi,
You won't need to define the AAA (ISE) server/group as per the links. When you come to configure the tunnel-group you'd select local (to use the local database). You would also have to create the users locally on the ASA.

HTH

[fbeye]

Thank you, that definitely clears up that portion of the document but hopefully not sounding too ignorant, what I mean is where would I define which IP address to use (dhcp) when the connection is established as well as which IP/Server/Port to define when connecting?

[Rob Ingram]

You would define the VPN Pool, then reference the VPN Pool under group-policy. Any user that successfully authenticates would receive an IP address from that VPN Pool.

HTH

[fbeye]

Would these be sufficient ;

For VPN Pool

https://www.cisco.com/c/en/us/td/docs/security/asa/asa72/configuration/guide/conf_gd/vpnadd.html#wp999102

For Group Policy

https://www.cisco.com/c/en/us/td/docs/security/asa/asa72/configuration/guide/conf_gd/vpngrp.html#wp1166190

And then either of your links for security?

[Rob Ingram]

Well actually the SSL-VPN link I provided gives an example for a VPN Pool and how to attach in a group-policy :)

Yes, these links you provided give good examples also.

HTH

[fbeye]

Well I am making progress but still so not there.

The SSLVPN method must be following a version of the ASA/ASDM that I do not have because none of it is adding up.

Where I am at is, on my iphone AnyConnect I can connect but it drops saying No License. On my Windows PC I connect and it works. I connect to the ASA via VPN but then it kills my Internet connectivity and I can not mount or do anything.

What I am seeing is it is configuring WEBVPN which I only have an image for Windows on my ASA but I want to connect via iPhone. Clearly there is a lot I am missing. My latest attempt, shown here, was the ASDM Wizard, Cisco Anyconnect SSL. My main concern and only internet is for, when I am on the VPN, I am able to access a NAS on 10.0.2.111 through the 10.0.2.115 IP on Interface 1/8.

Hi,

If you want to just tunnel specific networks you can use split tunnel. E.g:-

access-list SPLIT_TUNNEL standard permit 10.0.2.0 255.255.255.0

group-policy GroupPolicy_HomeVPN attributes
split-tunnel-policy tunnelspecified
split-tunnel-network-list value SPLIT_TUNNEL

You may need a license to connect from iPhone, you can check your license info under the "show version" and "show activation-key".

Ahhh, I knew about the Licensing but was assuming it was for larger deployment... It looks as if I do not have it for Mobile.

Oh I forgot to ask; I had every intention of following the SSLVPN Guide but everything before the “ASA CONFIGURATION” seems completely foreign to my ASDM. How do I implement the first portion?
