is there a way to access through ISP NAT?

the question is simple... i have an ISP which have all consumers behind a nat...

so you can imagine problems accessing network from the outside...

i'm downloading fedora, before installing amahi, i'd like to know, does your software offer something like logmein? (logmein not hamachi)

to explain better


i leave my server logged in
and i access from the outside, logging in by browser

BUT WITH PEER TO PEER CONNECTION (after logging in the "net" in logmein, the connection becomes peer to peer, like also messenger programs etc...)

amahi does not include this functionality. the VPN requires that you can forward a UDP port through NAT :(

however, you may be able to use logmein or maybe something else (skype screen sharing?), to any computer in your network.

yes i thought it, but logmein doesn't offer a linux server... ;( i can't understand their way... a browser client (also html compatible with everything) but a windows only server...


so i'll find a workaround ;)


tomorrow my little atom server will arrive ;) waiting for that moment to try your software, reading on your site seem a very nice software ;)

ah i know being ot,sorry but i think it's more "spammer" open another thread for a simple question ;)
is amahi compatible with both gnome and kde edition of fedora' (i ask cause i am a very old kde user, i used it since kde 1.x ;)

you can use amahi as a desktop as well.
if you do that, you can use any desktop you want, including kde, of course!

I am in the same situation (Italian Provider named Fastweb), here's what I figured:

1) accessing Amahi VPN server or web login, depending on your home firewall settings and/or ISP firewall if any is present (ISP firewalling you is different from ISP NATting you), should be possible from another connection to the same provider, see usually provider who sells NATted internet access have their own private IP network (thanks to IPv4 address running out they had to do so) shared by all their customer so if you connect from some other place with the same ISP you might manully add a route to your own ISP router address from there, thus being able to ping your own home network and establish a connection.
ask if you don't know how to do that.

2) accessing your Amahi server behind an ISP NAT from the public internet (any other ISP, with or without NAT) is possible only if you setup a tunnel to something that you can reach and in turn can be reached from anyone else, this might be a friends of yours with a connection to a non-NAT ISP setting up some tunnel server just for you or some other public service like this.

Personally I think that setting up an IPv6 tunnel might be the best option, I already posted a request for a one-click install of the gogoclient which sets up an IPv6 tunnel (capable of breaking thru NAT) to the GogoNetwork servers, very robust and high bandwith, so far the best public free service to do that that I've found.

this being said please rememeber that usually home ADSL connections are asynchronuous and have low upload rate, so do not expect to be able to read your files like you were connected to your own LAN.

Also you might want to change ISP (like me), I recently found out that searching for ISP offering native IPv6 connectivity provided the best offer on the market, I discovered some obscure Italian ISP offering native IPv6 connectivity on fibre connection (30Mb down /30Mb upload 8 Mb guaranteed, meaning 3Megabyte download/upload and 800Kbyte guaranteed) at 80eur per month this way while I am paying 40eur for a 7Mb/512K line right now, plus they support opensource/linux and offer MUD servers!?! needless to say all ports are open and no P2P blocking, 8 static IPv4 or v6 included,
maybe it's the trick to find the good ISP in your state/nation too.
