Hello,
Our current setup uses a ZyXEL ZyWALL 35 with two Netgear DG834G ADSL routers connected to the two WAN ports on the ZyWALL. Our office is in a fairly remote location so ADSL is our only viable method of providing an internet connection. This setup has worked quite well for the last couple of years but recently we have had the following concerns with continuing to use the ZyWALL:
- We are getting more remote users using Windows Vista and the ZyXEL VPN client doesn't work under Vista. ZyXEL won't give an ETA on when a Vista-compatible version will be out, but suggest it could be next year.
- The VPN has also not been the most reliable with Windows XP users - often it works but there have been random connection problems - sometimes it just doesn't work, despite ZyXEL confirming that our setup is correct.
- We would like to have more than two ADSL links in the near future (possibly up to four) and then use one for servers (Exchange server, etc.) and the other three to be load-balanced to provide web access to our users' workstations. Our current ZyWALL 35 only has 2 WAN ports.
We have now had more problems with our ZyWALL 35 unit and are looking to replace it immediately. Can anyone recommend a replacement unit that ticks the following boxes:
- is a hardware firewall
- has full IPsec VPN
- VPN client is Windows-Vista compatible - a must!
- has up to 4 WAN ports and allows load-balancing across some of the WAN ports (but not forced to load-balance ALL of the ports - want to use one for servers only, so some kind of static routing required) so we can connect multiple ADSL connections.
- will provide NAT so we can forward ports (eg. 21 to our FTP server, 25 to our Exchange server, etc.)
Cost is less of a concern over having a reliable unit that comes from an established manufacturer and ease of use (easy VPN client installation/use, good GUI interface to router, etc.). We are now a company with over 150 users, so are more than happy to invest heavily in a unit if it gives us what we want.
So, can anyone point me in the right direction?
Many thanks, Robert Stokes
