We have both and they really don't compete as an SSL VPN solution unless your Juniper SA is used as a Network Connect only box. When someone says "SSL VPN" it means different things to different people/companies. In the Juniper SA sense it's the full rewriter with lots of other features. Basically you can do remote access with only a browser, but it also does more. For other people it just means an IPSEC VPN that uses HTTPS in place of IKE for authentication and ESP (and possibly SSL for fallback) as a transport. If a vendor that has an IPSEC only VPN product adds the ability to authenticate their VPN with a web browser instead, they then market that as an SSL VPN. Netconnect is basically like this and compares similar to the dynamic vpn in Juniper SRX firewalls or Network Connect. It is not URL rewriter. Ron

I had the exact same problem except our servers were running 6.1R2.0. I found that *some* of our servers would not accept the ESAP update when using Firefox, however in every case when I switched over to Internet Explorer 7 the update worked fine. Another thing to check is that you have no errors on your ethernets. I found that an IVE with ethernet errors will usually work fine for users (might be slow though), however it severely affect any software updates (firmware, ESAP, etc.) and they most often will fail.
