Guys,
You have plenty of concepts in networking that are very hard to grasp.
And networking is my focus area.
In today's Internet any cool technology uses networking in some way or other.
My rich knowledge in networking helps me do several things with a lot
of constraints.
In several cases even if you pump in a lot of cash you cannot achieve
the goal you have without
?knowledge.
FWIW - another cool trick that works for my operations.
1. Pay Rs. 1000/year to MTNL (Mumbai) for a static IP Triband DSL.
2. I have my company DNS served by a gratis DNS service like
everydns.net (they were recently bought by DynDNS) but there are still
other free DNS hosting services.
3. Define a hostname eg. <dslwanport.mydomain.com>.
4. With full disclosure to client, define a port forwarding rule at
client router to let my staff enter into their network from
<dslwanport.mydomain.com>, directly from our office systems.
5. Next step remote network monitoring using above concept.
The Rs. 83.33/month for static IP is well worth it. Alternately, you
can map your dynamic IP via DynDNS as well but that would using one of
their domain names.
The static IP also allows me to come into my office LAN when I am on
the road, I point my client to <dslwanport.mydomain.com>.
FWIS, also take a look at TeamView, Logmein etc. for remote
administration/access (free for non commercial use).
