Policies fine-tune access to network resources and act at the global, group and user levels. Single IP addresses or IP networks are assigned to each object and you can have multiple entries for each one. A new feature is the Citrix portal, which replaces the ICA client with a Java app that’s downloaded on demand. Each can define all services, or you can choose from HTTP, HTTPS, RDP, VNC, FTP and file shares. You define what services you want to make available by creating network objects. For user authentication, you can use the internal database, but, as with other SSL-VPN appliances, there’s also support for NT domain, AD, RADIUS and LDAP authentication. You start by defining addresses for each port, default routes to the remote networks and, if required, static routes as well. Consequently, its management interface can only be accessed from a system connected to this port.įor testing, we placed some XP systems on the first port to act as remote clients and connected the second port to our LAN where our application servers resided. It offers four Fast Ethernet ports, but only the first can terminate SSL-VPN sessions. Unlike Billion’s BiGuard S10 (web ID: 100213), it doesn’t offer any firewalling capabilities, designed to sit behind an existing firewall and control access to services placed in a DMZ or a separate subnet on the LAN. It offers a reasonably powerful hardware package but, although there are no user limitations, SonicWALL recommends it handles no more than 50 concurrent connections. The SSL-VPN 2000 on review is aimed at businesses with up to 500 employees. So, this all has to fall back on IT for some reason.SonicWALL moves into this market with three appliances. Because apparently he doesn't trust the supervisors of the staff that are working from home.
The reason I asked the question to begin with is because my boss asked me to have users booted off the VPN after 15 minutes of inactivity, so we can see how often they are getting disconnected/logging back in so he can determine if people are actually working from home. Okay, so now that I know what SonicWall means by "Inactive" (IE: broken link), meaning my immediate supervisor (.the CFO.) wants me to do the impossible once again. I wonder if it's more 'broken link' detection than actual 'idle time'What happens if you turn off the wi-fi on your machine at home?įuricle - That was it! I just killed the wifi, and about a minute later the 'Inactivity Time' was showing 1 minute. There has to be a way to go about this though.I mean, why else would they have the 'Inactivity Timeout' option? I find it hard to believe there would ever be a way to detect the idle time for a VPN Client, as there is always something happening behind the scenes of any networked device. I reconnected to the SSLVPN and after 5 minutes the "Inactivity Time" still shows 0 minutes and the packets sent/received is continually incrementing, meaning there is data being sent behind the scenes that is preventing an idle time from accumulating. For lack of anything else to try, I did disable NAT Traversal to see what happens.unfortunately, the results are the same. I think you are on the right track about a keepalive packet being sent over the VPN, but I thought that the NAT Traversal settings you mentioned are for Site-to-Site based connections. The “keepalive” is silently discarded by the IPSec peer. Therefore, to preserve a dynamic NAT binding for the life of an IPSec session, a 1-byte UDP is designated as a “NAT Traversal keepalive” and acts as a “heartbeat” sent by the VPN device behind the NAT or NAPT device. IPSec VPNs protect traffic exchanged between authenticated endpoints, but authenticated endpoints cannot be dynamically re-mapped mid-session for NAT traversal to work. There will be some kind of 'keepalive' packet being sent between the client and the host, not sure where to look to configure it but can guarantee that's the problem!Įnable NAT Traversal : Select this setting if a NAT device is located between your VPN endpoints.
