Problem with two networks in one router

[vgklezakos]

Hello

I recently changed my company's router with a cisco 1941 k9 and i have a problem......

I have two networks the 192.168.1.0/24 in gig0/0 and 10.69.0.0/16 in gig0/1 Both networks have static ips

The most of the hosts are under the 10.69.0.0 but my dns server has ip 192.1.1.144 the problem is that although i can ping from one network to other i can not resolve netbios names from the network 10.69.0.0.

I already configured the ip helper-address to gig0/1

Any clue why is this happening???

Hi,

ip helper-address is only to send the requests to DHCP server, this is not for dns resolve.
You need to configure the domain-name and name server under the DHCP config.

ip dhcp pool OFFICE
network 192.168.12.0 255.255.255.0
domain-name networkers-online.com
default-router 192.168.12.1 !– gateway address
dns-server 192.168.12.100 192.168.12.101 !– DNS servers
netbios-name-server 192.168.12.99 !– WINS servers
lease 2 !– lease time

Please rate the helpful posts.

Both of my networks use static ips, there is no DHCP in my network, Do i still have to configure dhcp pool ???

Thanks

Hi,

no not for netbios resolution unless you want to send your hosts a WINS server IP address.

Can you try using ip helper-address to directed broadcast IP and get sure directed broadcast are enabled on interface.

I already have configured the ip helper-address to redirect all the broadcasts to my wins server how do i enable the directed broadcasts to an interface??

Thank you for your help !!!!! you were right i had only configured the ip helper address without broadcast forwarding

hi evangelos,

have you entered the dns-server ip manually at the workstations? cause then it should work, as if the clients know the ip address of dns server they dont generate a broadcast at all and therefore the router should route the packtes.

alternatively you can also edit your "lmhost" file on the workstations.
