Hi all
I have seen that there are often problems for the configuration about port forwarding.
I would like to give a small contribution even if I think I'm a lucky man (at least as it regards routers, switchs and so on).
Before buy a dedicated tool (modem+router or router all in one) I recommend to all those that own an old PC (more it is old and more it is better) to try this mini linux distribution.
http://www.brazilfw.com.br/forum/portal.phpfrom this site:
BrazilFW is a Linux mini-distro, designed for setting up network utility services such as internet connection sharing, firewalling, routing and wireless access points.
I have been using it for quite a lot years (first was called
CoyoteLinux) on a pc so powered:
PC Cyrix 166 (you don't smile, it is enough)
48 MB Ram (to find these so obsolete ram of memory has been the hardest part)
There is also now a HD recovered by other old PC of 1 GB (and don't smile again).
Configurations particular ANY !!!.
Hi has worked to the first hit.
Why not try?
In any case this application have very valid characteristics if whoever uses it it has the necessary knowledges about it
(in few words, it may works easy but also in a hard way if any have a little knowledge about IP,lan; etc).
The last, but not less important thing, is free

Best regards

So, God created the man.
It gave him a brain and a penis.
Unfortunately not enough blood to contemporarily bedew them
