Question about Routers
I tried portforwarding using portforward.com guide. but the problem is my local area network cannot see my servers using fqdn. other pc (internet, public and other computers not connected to my network that doesnt pass the modem/router) can see my servers.
if i go to my fqdn on my local area network i see the router config page. also other ports that are being forwarded are not working in local area
is there a tweak or config on the router/modem h5200?
i need help anyone?
Does your DNS server have your server fqdn in its tables, and does your PC have the address of your DNS server in its lookup table?
One test you can do is to use the hosts file to put the fqdn into and assign it an address this would let you know the the PCs can use host tables to do the translation then this becomes a DNS issue as opposed to a lookup issue and you cut your troubleshooting in half.
In other words edit your hosts tables (hosts file) with the entry (Example 1):
IPADDRESS FQDN ALIAS
192.168.10.2 somesystem.myhome.com. system
192.168.10.5 somesystem2.myhome.com. system2
This as stated will determine if you have a DNS issue or a lookup issue, because the DNS system will use host tables first and the do a DNS lookup.
Once this is done if it works then try this setup:
1) in your router set the DNS to capture the DNS of your ISP (normally the setting will tell the router to use the DNS given to it by the DHCP protocol.
2) turn on DHCP on the LAN side of the connection in the router and set the controls for proxy DNS service (using the router as the local DNS server also called caching DNS server), However set the router up to allow static IPAddreses and if possible to recognize the domain name of the local LAN.
3) set your servers up with static IP addresses and in their host tables set the fqdn up as stated above in Example 1
4) in your PC set the DNS to be the IP Address of your LAN side of your router i.e. 192.168.1.1 and if needed set the host tables of all PCs to the server addresses, fqdn, and aliases this way if DNS fails the system will at least have the host tables to use.
I hope this helps.
