Routers / Switches :: Error About IP Equals Subnet

Apr 18, 2012

Following instructions on How to add a 2nd router to network.This error will not let me complete and save the definition. Changed 2nd router IP address to static, disabled DHCP, added 1st router IP as default gateway, set subnet mask to same as 1st router. Problem occurs in next frame called 'Network Setup' it is requiring a 'router IP' & subnet mask again and will not accept either the 1st or 2nd router IP address - gives the "IP equals subnet please correct" error or "LAN & WAN IP addresses are identical.

Cisco Routers :: RV110W - Error / Destination LAN IP Cannot Be Same As Router IP Subnet

Oct 11, 2012

In Cisco RV110W I configured 2 VLANs, one Net) and the second with only one fixed address, which is configured in the DMZ Zone. I enabled in Cisco "inter-VLAN-Routing", that is described "routing between the seperate VLANs on the Cisco RV110W" I can Ping the server in one direktion, in the other I got an error. That is all expected and ok! All other expected abilities work well !Now I want to see the server from green net . (firewall in the server is off)I configured Networking/Router with exact the Hint values and got an error : "destination LAN IP cannot be the same as the router IP subnet"

Routers / Switches :: 2 Routers On Same Subnet With DD-WRT VPN Tunnel On Second?

Mar 13, 2012

How to set up a home network with 2 routers, where R1 acts as the DHCP server and R2 is basically a switch, connected LAN to LAN and everything is on the same subnet. Currently I have a different setup:Both routers have the DHCP server enabled and I connect R2's WAN port to R1 LAN. Therefore I have 2 subnets. Now my special requirement is that R2 is a DD-WRT router, which establishes a VPN connection to StrongVPN, so that all internet traffic via R2 is encrypted and goes through the StrongVPN server. Now my question:If I change my router setup to the same subnet, meaning R2 connects LAN to R1 LAN and I disable DHCP server on R2, will R2 still be able to establish the VPN connection?

Routers / Switches :: Routing Traffic Across Nics From One Subnet To Another?

Sep 25, 2012

I have an issue with some traffic routing:

Machine A | Machine B (Win 2008 R2) | Machine C

Start: > (NIC 1) - (NIC 2) > the question is how do i get traffic from Machine A to Machine C. I've tried various 'Route ADD' cmds but no luck so far. So was hoping someone out there could shed some light for me?Machine B is a AD/DNS and can talk to the entire 10.14.137.x range but has no forwarders set up in DNS. And does not act as a AD/DNS server for the 10.14.137.x range. It fills these roles only for the 192.1668.5.x range.

Routers / Switches :: Network Subnet Range To Wide For Vpn?

Jun 23, 2011

I have a supplier which i need to connect a site to site ipsec vpn connection to (from a draytek router). I have already done this on our main site with no problems using the local ip details of and subnet however i need to do the same on our DR site which uses the ip details of and subnet of Our supplier told me the is already used at there end by a different customer so we are unable to connect the vpn and communicate (in theroy we can connect but our supplier cannot reply). We can setup a connection to another spare server on a different address using a different subnet but effectivly this would mean that communication would stop at that server and communcation to the overall network or specific server the supplier needs access to (on the network) is not possible. I was thinking maybe an internal vpn server to server connection through win server may do it, 2 nic cards or routes in the server routing table but this all seems a bit messy. Our network consits of win 2003 and 2008 R2 servers and is basic network with modem-vpnfirewall-switch and devices on the internal network connecting to the switch.

Cisco Switches :: SG300 Not Reachable Beyond Subnet?

Feb 6, 2013

I'm trying to configure a SG300 to be reachable beyond its own subnet. Its IP address is configured by DHCP to It is possible to ping the switch from the same subnet but not from outside. The switch is set to layer 2 mode. All routing should be done by the gateway.
Here's what I have checked so far: The default gateway and netmask are set correctlyThe gateway can ping the switchHosts in the subnet have connectivity to other networks through the gateway (i.e. gateway configured correctly)Administrative interface > IPv4 interface shows the correct ip address, netmask, and gateway (greyed out because it is assigned by DHCP)the switch can ping other hosts within the same network  
Is there some kind of firewall setting that prohibits the switch to respond to ip packets from outside the subnet?

Cisco Switches :: SG300-28P - How To Enable NetBIOS Packet Forwarding Between Subnet

Oct 11, 2011

I recently purchased an SG300-28P.  I have 2 VLANS/subnets that are successfully routing between them.Machines on both sides can ping each other just fine, but none of the usual Windows/NetBIOS browsing is possible.  I've recently learned that NetBIOS is not usually forwarded between subnets.  How would I enable NetBIOS packet forwarding between my subnets?
Reading the manual, it seems like enabling UDP Relay might be the answer but I've been unable to get it to work (same with DHCP relay).

How To Connect 2 Routers LAN - WAN And Create Subnet

Sep 8, 2012

I'm trying to connect two routers and create a subnet but failing due to a little knowledge but no real understanding! I've read the ultimate setup thread loads of times but can't get my setup to work.

Here's the setup I'm trying to build:

Internet -> Master ADSL modem/router (No NAT, no DHCP) -> Slave cable router (NAT, DHCP)

I want to connect 3 Xboxes to the master router with external IPs to avoid the whole "moderate/strict" NAT nightmare. Then I'll connect everything else (PCs, Macs, wireless devices etc) to the Slave router which will assign IP addresses and do the NAT thing. Both routers are Netgear N150s (master is ADSL, slave is Cable).

Here's what I've tried so far:

Master router:

All IP addresses supplied by ISP
Internet IP: xxx.68.160.143
DNS: and
Router IP: xxx.68.160.142

Cisco Routers :: Connect To RVS4000 With Wrong IP And Subnet

Feb 21, 2013

I tried to update our production switch over the weekend with a newer unmanaged Gigabit switch. Everything was fine after the change and the network had a noticeable change in speed.But when I came back in on Monday the Internet was down. So I tried trouble shooting the switch to see if there was a loop or something like that and put it into managed mode so I could look at the config page and take advantage of the STP function. When trying to get to the config page I entered the default IP into my browser and a logon appeared so I tried to login and it failed then I noticed that the title of the browser tab said RVS4000. So out of curiosity I entered the creds for the router and lo and behold it let me in to the router. The router has a static IP and is using a different subnet then the default IP of that the switch has. I have put the old switch back and removed the new one from production but can still get to the router with either IP, it's static address and the 2.1 address.

Cisco Routers :: Connecting 2 RV042 To Different Subnet And DSL Connections?

Small office, 2 RV042, 2 DSL connections. 1 is used striclty for the business side, and the other is for our CCTV network. They also have seperate DSL connections as we have 2 external IP address for clients to connect remotely. We don't want to take away our exisring setup, but would like to bridge both networks so a few of our internal clients can connect to our CCTV network and use some of the devices. Right now they come in on VPN but its not as fast.Is this doable without adding additional hardware? Both networks need DHCP enable as well.

Cisco Routers :: RV220W - Routing IPv6 Subnet

Feb 27, 2013

I have a few questions regarding IPv6.

Question 1.
I have no idea how to route IPv6. My provider has provided me with a subnet. This subnet is for example 1:1:1::/48

The router of the provider is located at 1:1:1::1 and my router should get 1:1:1::2(Cisco router). Every subnet I want to create must be routed by 1:1:1::2, for example if I want to create 1:1:1:1111::/64 it needs to be routerd by 1:1:1::2

How do I configure this on the RV220w?
Question 2.
I have the possibility to create vlans on the RV220W. I can configure IPv4 addressen per vlan. Only for IPv6 this is not possible.How do I configure this or when will new software be released to configure this?Or do I have to edit the configuration file?
