ssl vpn or vpn into ocs

[adboy]

i am having problem convincing my security tm on opening the firewall ports
for \ocs external access to the edge server.

so i am looking at solution of ssl vpn or vpn ;into the dmz or internal
network to connect to ocs, anyone seen or done such a solution??

I had tried using F5 sslvpn to the edge server (and without the edge server)
, and was able to get the im working. Audio and video get connected for about
5 sec before being dropped. internally, all features work well on the
intranet. We had open all ports from the dmz (where edge and sslvpn endpoint
reside) to the int network where ocs server reside.

Talk to your firewall guys again, using the Edge Server and a properly
configured firewall is far better than using a VPN solution.

If you really need a VPN, why not just use ISA server as your
firewall/VPN server?

Hi adboy!

i think i have had a similar problem some time ago.
External calls were connected, worked some seconds and then collapsed.
Then it was the fact, that the dns names of the external interfaces of the
the edge servers could not be resolved from the internal network.

But in fact, i agree to Thomas, a normal VPN solution (PPTP / L2TP) would be
much more easier. Some hardware vpn server with special software clients are
also avalable on the market. Doing the VPN via SSL is much more complicated
than it must be.
