Configuration of Webvpn

I need some help on Webvpn as I have never configured one on an ASA. I have an ASA 5510. It has around 8 IPSec tunnels already running on it. I want to configure Webvpn for some users of that company who may be using public PCs over the upcoming holidays to access a particular website in the corporate network. So I will be giving access to only that URL. Reason why I am not giving them access through Remote Access IPSec vPN is that some of them may use public PCs to access the site. Hence I have decided on Webvpn access to them. Please advise if that is right thing to do. Also, is there any problem if I configure Webvpn on that ASA even if there are around 8 L2L tunnels running on the device. Another thing I want to know is that do the Webvpn clients need any assignment of IP address form an IP Pool like IPSec RA clients. A brief descritpion will help. Any help is appreciated.

Re: Configuration of Webvpn

There are different flavours of SSL VPN:

Clientless (WebVPN)

Thin Client (WebVPN+port forwarding)

Thick (SSL VPN) Client

For the first two options no IP Pool needs to be defined. That is only required in the Thick/Full SSL VPN Client configuration.

SSL/IPSec VPNs can co-exist with each other without any issues.

This is a configuration example for Clientless:

Yes you can do that.Infact that how its done in most cases.

If you are using ASDM from outside then you will need to change ASDM port on ASA.

Re: Configuration of Webvpn

Thanks Farrukh. Just wanted a second opinion on what I am going to configure. Thanks for pitching in. Antoher query I have is that will it be ok to enable both IPSec and Webvpn on the outside interface of ASA? I have ISAKMP already enabled on the outside with around 8 IPsec tunnels in operation. And I have to enable Webvpn on the outside now. There will not be any problem right?

Thanks for your time devoted to my query.

Re: Configuration of Webvpn

Yes as Iftekhar said you can run both on the same interface without any issues. SSL VPNs use port 443 (SSL) whereas IPSEC VPNs use ESP/UDP500/4500.

However If you want to run ASDM (ASA GUI) and SSL VPNs on the outside interface, this causes a conflict, as both use port 443 by default. To make this work you need to change the port for either webvpn or ASDM, please look at this link:
