its every time overlapsing or dont work if i change router ip, internet ip address, default getway
Laptops cant ping other PCs and etc
Hi @kostiantyn-shai,
You are configuring an IP address in the same subnet on two separate router interfaces. Example:
You are trying to configure router like this
It is not valid design to have same IP address outside of a segment.
I don't know your design, but I would suggest you edit the 'WAN SIDE' and change IP address to a different subnet or just set it to DHCP if you have no internet connection in your lab, like this:
This is why it won't let you save the config.
--------------------------------------------------------------------
Edit:
I just had a look at the PT file and I see what you are trying to do now. This is what you need to do:
- Configure WRT300N Wireless Router with LAN IP address of 192.168.40.1 with mask of 255.255.255.0.
- Configure DHCP in the same /24 for LAN clients/hosts
- The link between WRT300N and Router-PT needs changing. You have it connected from Router-PT fa1/0 to WRT300N 'LAN1'. You need to use another interface that is different, which will require the opposite of a straight-through cable (hint)
- Configure WRT300N under 'Internet Setup' with Static IP. This IP needs to be in the 192.168.50.0/24 subnet and use the default gateway of 192.168.50.1.
- Configure Router-PT so that it knows how to reach 192.168.40.0/24 through Fa1/0
- Fa1/0.40 on Router-PT needs changing. It needs to be in VLAN 1 not VLAN 40.
If you can work out the above you can get pings working between Laptops on WRT300N and PCs. Pings between computers and servers do not work by default, servers block ICMP in PT.
Let me know if you have more questions
