We have a client where we have to replace a router ( Cisco 1921 Series) which had failed. We had to replace it wit Cisco 841M router since 1900 series is end of sale. As the earlier router had failed, we do not have any information about configuration But the details of the case are as follows. The router has 2 x WAN ports and 4 x LAN ports
They have an internet line from an ISP . The ISP has given them following details while the line was commissioned. It is a dedicated 20MB 1:1 line. The IPs provided by ISP were
WAN IP Pool 115.149.74.108/30 Gateway 115.149.74.109 Subnet mask 255.255.255.252
LAN IP Pool : 48.249.73.160/29 Gateway 48.249.73.161 Subnetmask : 255.255.255.248
The IPs are for the sake of example only. Not the real IPs.
Customer has a LAN network with IPs 192.168.50.0/24 The router LAN port is assigned 192.168.50.254
We assigned 115.149.74.110 on one of the WAN ports. The LAN port ahs 192.168.50.254. We have set route properly and we are able to browse the internet. The PCs have LAN IPs and 192.168.50.254 as gateway. We are using the DNS Server IPs given by ISP.
The customer also has a Video COnf SYstem. The LAN IP assigned to it is 192.168.50.119.
From outside, people dial 48.249.73.162 to get connected to VC System.
Now we need to configure access to Video Conf system through the internet.
