IOS SSL VPN...Is it even possible?

Hello all,

I have a 3745 router with IOS AdvEnterprise 12.4-15-T6 and am trying to deploy SSL VPN over it.  I've heard varying reports, some say it is possible, others say it is not.  It seems that the 3745 is a strange router of sorts, kind of falls in the middle of the x600 series and the x800 series.  I am using SDM 2.5 and I have installed the sslvpn-win SVC manually on the router, yet when a user goes the the web page and attempts to open a full tunnel, the java app never completes.  I'm really stumped on this.  The end result is to enable access to a CallManager in the system from abroad, using IP Communicaotr.  EasyVPN would be fine but alas no support for Windows x64.  Any help on this would be greatly appreciated.  Thanks again.

If there is additional info I can provide please let me know. 

Re: IOS SSL VPN...Is it even possible?

Hi,

Yes. Cisco 3745 router with An advanced image of Cisco IOS Software Release 12.4(6)T or           later will support SSL VPN.

Find the URL that will help you to configure webvpn in your cisco router.
