Routers / Switches :: Routing Between Two Networks With Same Subnet?
Mar 7, 2012
Two networks. NetA: IP subnetID 10.101.x.x subnet 255.255.0.0. Devices have static-assigned IP's. Only DHCP runs on wireless AP for wireless client connection. IP addressing scheme set by hardware vendor, so not under my control. NetB: IP subnet 10.x.x.x subnet 255.0.0.0. Campus LAN and also not under my control. DHCP supplied addressing. how to get NetA devices to route to NetB?I would like to be able to provide Internet access (via NetB)to NetA devices.
Start: 192.168.5.9 > 192.168.5.5 (NIC 1) - 10.14.137.130 (NIC 2) > 10.14.137.128So 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.
I need to make some changes on our network. We currently have two sites 150 miles apart we join both by way of fiber and on each side we have Cisco 3750 stack switches, configure trunking for all V lans on one port in site one then through the the long haul fiber to site two with site one using 10.1.1.30 and site two using 10.1.1.40 as their default gateway, with static routing all V lan sub nets to the other sites default gateway life is good.
My question - seeing how we have sites using the same sub net 10.1.1.x to trunk all data to each site through switches; we need to now change the network and add each site to the MPLS network, site one switch 1 IP address 10.1.1.30 going to MPLS router one with FA0/0/0 using IP 10.1.1.31, site two having switch 1 IP address 10.1.1.40 going to MPLS router one with FA0/0/0 using 10.1.1.41. I need to know will this work.
We have the same sub net in each site 10.1.1.x to the MPLS routers then the external router interface connecting each site to local switches, will this cause any problems by using the same local sub net for each site?
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?
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 192.168.1.2 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.
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 192.168.1.0 and subnet 255.255.255.0 however i need to do the same on our DR site which uses the ip details of 10.1.0.0 and subnet of 255.255.0.0. Our supplier told me the 255.255.0.0 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 10.1.0.0 255.255.0.0 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.
One of our office´s PC is connected to the network and shows 2 networks, but we have only one modem and one router....and no internet access only in that computer. I had restarted, disconnected, shut down and nothing.....what can I do? I also connected it to another cable form other computer working correctly and didn´t work.
My workplace currently has one AD Forest. Slowly we have drifted in to two slightly separate businesses and my boss wants us to create a new AD Forest and segregate the users doing each business. Although we will all be in the same office, each side will authenticate to a different DC. The problem is, that we have some resources that still need to be shared and I would like to share them as eloquently as possible without converging the networks too much. The two networks will be in the same server rack but they will logically appear as this:Forest1.local (original)
-Cable Internet -- Router A (192.168.1.x) -- 48-port switch A -- PC/Phones/Domain Controller AForest2.local (new)
-Cable Internet -- Router B (10.1.1.x) -- 48-port switch B -- PC/Phones/Domain Controller B.
The problem I have is that the users in the "new" network need access to a shared folder, shared customer DB, and shared printers on the original Domain Controller, named "DC A" above. I have complete control over both networks but cant figure it out the best way.My main concern is physical access between the networks. How will a pc on the 10.1.1.x network know where printer 192.168.1.2 is? I thought about creating a forest trust in order to assign proper permission but how will they resolve the names on a different subnets? The two "routers" are just simple SOHO type routers so I cant do much there. I thought about connecting the two switches together but don't know if that would work. Wouldn't the data just get passed to the default gateway (router) anyway. The router would then just drop it. I also though about using the 2nd NIC in each DC and connecting them in each other's subnet. But again Im not sure if it matters if the DC's can reach each other or if the PC's would have to be able to reach the other subnet etc. I also thought about just creating some kind of VPN (hamagachi) or whatever to go out into the internet then back into the other router to the network.The problem is wouldnt every computer wanting to access the shared folder have to have this setup. I would like to limit setting things up on workstations and just limit config to the DC's if possible.I basically just want users in subnet two to be able to map a drive and access printers on DC in subnet one.
I live in a school residence with a roomate and we both have an internet connection in our rooms but it's two separate networks since we can't see eachothers pc on the network. Both our pcs are connected to a switch and those switches are connected to the two internet connections. I would like to know how to bridge those two networks using a router in the living room. I would also connect a printer and an xbox to the router so we can both access the printer, the xbox can access both pcs and we can access eachother's pc.
I'm going to move offices into a shared situation with 3 companies. Each company will want its own private network so there's no snooping between companies. I am planning on using VOIP for the phone system (Nextiva cloud based). Is it possible to set up the system so that each company has access to the VOIP system but yet remains sequestered in the their own network for everything else. I was hoping to do this with one data port at each workstation using Cisco SPA-303 phones. The way I understand this, is that the phone plugs in to the data port and you daisy chain the workstation off from each phone. Is this possible to do this while having the system I described? Another wrinkle is that I'd also like all the networks to be access shared printers.
how do i create 2 networks using 1 cable modem and 1 router and i would like to add a firewall thinking of using xywall usg20 for the firewall..... the issue is i have a small business with 1 point of sale and1 back office computer.(network1) and i would also like to use an air port wifi to offer wifi to my cleints on a seperate network(network2) not allowing access to network1 and i want a firewall on network 1 to protect the back office and pos system
I have 2 nics in my win7 system, NIC 1 connect to leased line and NIC2 is connected to organization LAN for internet. Both the ip add are in same subnet. when both the cables are plugged in to nics, leased line link connected to nic1 goes down. It wouldn't come up untill the cable from nic 2 is plugged out.Basically i wish to be connected to both the networks simultaneously.
I'm wanting to use the SRP527W (from Telstra) to route a block of assigned internet addresses (/29) over the WAN internet IP address. Is this possible on the 527W, or does it only do NAT routing?
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?
I've been playing around with the Cisco RV180s for a while now and have come across a problem with the subnet calculation in the static routes and routing table. Essentially, if I configure up a static route for a /16 it's entered in the routing table as a /13. If I add a /24 it's entered in the routing table as a /16. I haven't tested every subnet size and combinations but this looks like a fairly fundamental maths bug.
As a side note, I notice that the 1.0.1.9 release notes state the removal of SSH Server, however, I can not find any reference to it's existance prior to 1.0.1.9, did/does it exist in 1.0.0.30 and if so where? .
Screenshots are below and an extract from the configuration file for reference.
I'm trying to configure a SG300 to be reachable beyond its own subnet. Its IP address is configured by DHCP to 192.168.2.2/255.255.255.0. 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 192.168.2.0/24 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?
Just got a new SGE2010P layer 3 switch. I'm trying to configure Vlan to reach a few subnet. I have the original 192.168.1.0/24 as vlan1. I want to reach our WiFi subnet 192.168.10.0/24. The WIFI router is directly connected. It's new for me as the previous Job i was sorking with a ws-3750-48.
i did from console change my switch to layer 3 mode... ( i want it as the DGW for each Vlan)from the web interface, i create a vlan4 for our WIFI Next i go to ipv4 to add an IP address to vlan 4 like 192.168.10.254 /24 As soon as I apply the IP the switch stop responding, Ping request time out.. i need to reboot the switch..
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).
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: xxx.xxx.3.xxx and xxx.xxx.6.xxx Router IP: xxx.68.160.142
I'm trying to set up 2 subnet with two RV042 routers. One router will act as a gateway and both WAN ports will be used by two different isp connection. The first router (gateway) LAN IP will be 192.168.0.1/24. I would also like to set up another router behind the gateway with with separate subnet 192.168.1.X/24. And I would like clients on the 192.168.1.x subnet to use the internet through the gateway router and clients on the 192.168.0.x subnet to access resources on the 192.168.1.x subnet. Am I able to do this with two RV042?
I'm trying to setup this router with my IP range 192.168.100.1 to 192.168.101.254 but if I try to enter a subnet mask other than 255.255.255.0 I get the error - Invalid subnet mask. It should be 255 for given class of IP address at 255.255.xxx.0.
Every other device on my network allows that subnet mask, why not this router, it's stopping access from my 192.168.101.x devices.
I have RV042 Router, I'm using only one Internet conection, I'm using IP group like this 192.168.95.x, my DHCP setting use 192.168.95.120 to 192.168.95.240, but in this time I have 245 workstations (may be I will have 25 additionals workstations) and some times I see IP conflict message in my current work stations.
I had read about SUBNET like response about my problem, but I'm not sure about that and how to make subnet with my RV042.
We connected to locations to the RV042 by setting up 2 Gateway - to - Gateway VPNs - both locations can communicate with the RV042 and devices within the local LAN of the RV042 - however at the moment it is not possible to send traffic from 1st VPN Location to the 2nd VPN location
I have a RV042 with multiple subnet, 192.168.10.0 and 192.168.9.0. 192.168.10.0 is assigned to the LAN, 192.168.9.0 is created under multiple subnet. Both subnet can access Internet by accessing IP address, but 192.168.9.0 cannot access Internet by using host name. It looks like DNS is not working for the 9.0 network.
I have one router (A) (192.168.0.xxx) that serves as internet gateway. Another two routers (B & C) (192.168.1.xxx & 192.168.2.xxx) that serves two sub-net/network, are connected to this router (A). How can I set it up so that PCs in sub-net C are able to print to network printers in sub-net B? Pls note that I do not have full control over router A.
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 192.168.2.1 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.
