Ciao
Vi posto alcune immagini e info riguardo il firmware in oggetto.
Il firmware lo potete scaricare da
qui
E' NECESSARIO RESETTARE IL ROUTER DOPO L'AGGIORNAMENTO.
I SETTINGS NON SONO COMPATIBILI CON IL FIRMWARE ORIGINALE.
Con questo firmware il dg834g può funzionare anche come modem senza NAT, se lo settate come modem sembra il dg632.
Nel menù del router, completamente in inglese e non in italiano, troverete un nuovo sottomenù
ExoVii 
Tutte le nuove funzioni hanno una breve descrizione in inglese mooolto utile, ma vi mostro le immagini ...
1) Autoreboot
The Autoreboot script can reboot the router if the Internet connection fails.
The router will reboot if the specified address could not be reached more than n times.
Delay between tries can be modifed.
Warning: if you enter an unreachable address, if the number of tries is low and if you checked the 'autorun' case, your router will enter an endless reboot loop.
If the router enters such a loop, you'll have to access it through SSH when it starts and type
killall autoreboot
Next, you'll only have to access the administration panel to change the Autoreboot parameters.
When Autoreboot is started automatically when the router starts, it waits for 20 seconds in order to give you the time needed to operate in case of endless reboot loop.
Start Autoreboot at boot time:
If checked, the routeur will reboot if conditions described above are filled.
Address:
Address of the host to contact at each try. This address MUST reply to ICMP requests (ping).
Delay between each try:
Delay in seconds between each try.
If host is unreachable, delay between each try will increase by a few seconds due to ping timeout.
Number of tries:
Number of failed tries before the router reboots.
2) DHCPD
DHCPDHelp
Some additional parameters for the built-in DHCP server.
Main DNS server:
Main DNS server for your DHCP clients. The default value is the router internal IP address, but you can change that to use another DNS server.
Lease time:
Maximum time (in seconds) a computer of the LAN can use an IP address without requesting the DHCP server.
Additional parameters:
Here you can define some additional parameters to transmit to the DHCP clients, for example a secondary DNS server.
More informations on the udhcpd website.
3) HTTPS
HTTPS is a secured protocol which can replace the standart HTTP protocol to access web sites. It can be used here to access the administration panel of the router.
Administration panel protocol:
HTTP protocol is the default, non secured, protocol. HTTPS protocol is secured by cryptography.
Private key:
Private key of the HTTPS server.
You could use OpenSSL to generate it.
Certificate:
Certificate of the HTTPS server.
You could use OpenSSL to generate it.
Generating private key and certificate for the server:
You could use OpenSSL.
Steps:
Certificate request:
openssl req -new -out cert.csr
Private key:
openssl rsa -in privkey.pem -out key.pem
Certificate:
openssl x509 -in cert.csr -out cert.pem -req -signkey key.pem -days 365
Remove unused files:
under Windows:
del cert.csr
del privkey.pem
under Unix/Linux:
rm -f cert.csr
rm -f privkey.pem
The file key.pem contains the private key.
The file cert.pem contains the certificate.
4) HTTP Tunnel
HTTP Tunnel Help
Here you can control the HTTP Tunnel server (hts).
Start HTTP Tunnel server at boot time:
If checked, HTTP Tunnel server will start when router starts.
Port:
Change the HTTP Tunnel server port (default: 443).
If you want to use another port, be sure no other application make use of it.
5) Loopback
Loopback Help
Here you can apply firewall forward rules for LAN users.
For example, say you have a DNS alias on your public IP:
www.mydomain.com
Say you have a Web server on your LAN. You already set up an inbound rule to authorize external computers to access your Web server. External users type
www.mydomain.com for the address.
If internal users try the same address, it won't work, they will be stopped at the router admin panel.
You have to activate Loopback to permit internal users to connect to
www.mydomain.com (which is on the same subnet).
Activate Loopback:
If checked, Loopback will be activated on next router boot.
Note: If you change some firewall inbound rules, you'll have to reboot the router to make them available to your LAN users.
6) No-Ip
No-ip dynamic DNS
No-ip account update.
Enable no-ip service:
If checked, account aliases will be updated with the WAN IP of the router.
Email:
Email address you use to log in
www.no-ip.com.
Password:
Your password on no-ip.
Aliases:
Aliases list for your no-ip account.
7) NTPD
NTP daemon Help
Here you can control how the router synchronize its clock and if it must act as time server.
Act as a LAN NTP server:
If checked, the router acts as a time server so computers on your LAN could synchronize their clocks.
Go to time zone parameters:
This link brings you back to the configuration page for router timezone.
Time sources:
Specify time servers and/or time servers pool.
If you need more informations about time servers, please go to
www.ntp.org.
8) SNMP
Simple Network Management Protocol Help
Here you can control the SNMP server.
Start SNMP server at boot time:
If checked, SNMP server will start when router starts.
Community:
Name of the read community. You'll need this information when using a SNMP client.
System contact (sysContact):
System contact (aka administrator) email.
System name (sysName):
The name of the system.
System location (sysLocation):
The location of the system.
9) SSH
Secure SHell Help
Here you can control the Secure SHell server (dropbear).
Notes:
SSH username is ALWAYS root.
SSH password is the same as admin panel password. However, if the admin panel password is modified, SSH password will be resynchronized at next router reboot.
Start SSH server at boot time:
If checked, SSH server will start when router starts.
Port:
Change the SSH server port (default: 22).
10) Wake On LAN
Wake On LAN Help
Here you can wake up the computers of your LAN (only wired !).
WOL workstations:
WOL compatible workstations list. These workstations can be awaked by LAN.
MAC address is XX:XX:XX:XX:XX:XX where X is an hexadecimal number (from 0 to F).
Import DHCP leases:
Import of MAC addresses which are declared in DHCP leases.
Spero di aver fatto cosa gradita ... buon divertimento
