Protocols / Routing :: Connect Two Net On Same Lan With Two Gateways

Apr 28, 2012

I have two different networks on same LAN.One net has public 2xx.x.x.x IPs (some on DMZ, they are servers with their own internal firewalling) and goes through a GBeth switch to a Cisco 25xx router for accessing HDSL modem with several HDSL trunks and then Internet. That router is configured to let external IPs access only DMZ IPs, of course.The other net has 192.168.x.x IPs and goes through another GBeth switch to a DLink router to access ADSL. Mainly for download traffic at a low flat cost.I would like to have a way to let the 192.x.x.x machines access the servers on the DMZ of the 2xx.x.x.x net without going outside the physical LAN. The servers host mail services and so sending heavy attached documents needs a hi-speed LAN connection and certainly not the ADSL upload capability. Not to say about servers web contents maintenance.

Cisco Switching/Routing :: 5505 Inter-vlan Routing With Multiple Gateways

Feb 15, 2013

We have two Cisco 5505 firewalls connecting to two ISP's . The two internal LAN's on the firewalls are & We also have a Cisco C3560x layer3 switch with vlan interfaces 184.3 & 186.3. We have two DGS-3100 Dlink layer 2 switches connecting our users to the Layer 3. Ip routing is enabled for intervlan communication & I can reach the Switch interfaces & firewall gateways from machines on both on the vlans.We have pbr enabled on the 3560 & users only on the .186 network can get to the internet. The switch is running the ipservices license & the sdm template is "desktop routing" .

Users on the .184 cannot access the internet but we can ping the layer3 interface & the firewall gateway. [code]

Cisco Switching/Routing :: ASA 5510 / Routing Mobile Users Via VPN To Different Gateways

Oct 6, 2012

I have mobile users using air cards that connect to the network with a VPN product called Net Motion. Our  firewall is a ASA 5510. Once connected to the Net Motion VPN server the user will get a DHCP address from our network. In the past we could not get the VPN tunnel to complete since our layer 3 switch (3750G IP services) has 3 egress points and the egress point that we needed the VPN traffic to go out of is not the default gateway. To solve this we had the air card carrier set switch our air cards to static IP addresses and using route statements for the public IP addresses and access lists we got it to work.
The problem with this is that every new air card we provision needs a static IP address. My question is would policy based routing work in this scenario? The problem has been that the VPN tunnel was not able to complete the negotitaion phase as the traffic came into the switch and was trying to go out the default gateway. The VPN client wont get an internal IP address until the VPN tunnel is created.
I would like to get away from using static IP addresses.

Protocols / Routing :: Cannot Connect Using Real VNC

Feb 4, 2012

I am using RealVNC, have the Viewer and Server installed on three systems on my home network. I have a laptop which I am trying to use to connect to either of my two PC's, but cannot get them connected.With that being said I did have some luck with RealVNC as I have the 5900 and other ports forwarded and was able to connect with my Android tablet and Android Phone to the my two PC's and laptop with no problems....well kind of. I did have issues with this at first till I figured out I had to use a 142.*.*.* ip address because my network ip adresses were behind a NAT IP.Now back to the connecting my laptop to my two PC's issue.I have tried using the 142.*.*.* ip address and I have tried using my network ip 192.*.*.* to no avail. I just can't seem to connect.

Protocols / Routing :: Why Can't Connect To The Internet Right Now Using IPv6

Feb 16, 2011

The whole thing about IPv6 has been out for what is probably a couple of years now. But I find it very odd how even my newest modem/router can't even support it yet. Why on earth are manufacturers such as Netgear holding back so much on making their products IPv6 compatible? The IANA has just about given out what is left of the addresses, and we still have time to adapt by working our way over to IPv6 as it can work simultaneously with IPv4. Companies have been given years to prepare.

Why can't I connect to the Internet right now using IPv6? Not only is my router holding me back, but will my ISP hold me back as well?

Protocols / Routing :: Using Static IP Now Wireless Printer Won't Connect?

Jan 8, 2011

For some reason, our router donwstairs was kicking one or more of our (4pc's downstairs, one occasionally upstairs) off. My son connected another router upstairs and then created a static IP for everything. It seems when he did that, our Brother 2170 wireless printer quit working. We've tried everything to get it going again and nothing works- even Brother didn't get it rectified. Earlier today, my son finally got it working, connected directly to the router to get the static IP on the printer (I guess). But when he disconnected it (hardwired) from the router, it won't work again

Jul 26, 2011

I have set up several types of servers on my computer (ftp, game servers, web servers, etc).

I have had a problem with people connecting to any of my servers. I know for a fact I have port forwarded correctly (I have checked 12 times, and I have never had a problem port forwarding). I know it's not my firewall, the problem persists when I completely shut it down.

I had an ftp and web server working about a week ago. No one can connect to any server, be it ftp...web...etc.

My router is a Netgear WNR2000v2

Protocols / Routing :: Trying To Connect Wirelessly To BT Home Hub Via A USB Wireless Adapter?

I am trying to connect wirelessly to my BT Home Hub via a USB Wireless adaptor. The homehub works perfectly and I have other laptops in the house connecting via the wireless networkHowever, this is the problem. The Wireless connection status shows as good but packets only being sent and not received. Therefore when I load Internet Explorer, I get WebPage Not availableI notice that my IP address is starts with 169 and researching forums suggests that this is the problem and it should start 192? I have tried all sorts of things but simply cannot get this resolved. If I plug the HomeHub into the laptop directly, the connection via the ethernet cable works fine.

Protocols / Routing :: WRT54GC - Getting Wireless Signal But Cannot Connect To Internet?

Mar 9, 2013

I had a power outage while online and when power resumed, I was no longer able to connect to the internet via my wireless router. My laptops (I have 2, work and personal) both receive the wireless signal from my router (a Linksys WRT54GC) but I get a 'DNS lookup failed' error message when trying to access the internet. My standard set up was Arris cable modem-->Linksys router-->Laptop but I've had to go cable modem-->Laptop via Ethernet in order to access the internet.

Both laptops are running WinXP Pro, SP3 and I ran 'ipconfig/all' on my work one, once when connected via Ethernet and once when I had my wireless connection enabled (but again, not connected to the internet). Results below.

Ipconfig/all when connected via Ethernet to cable modem:

Cisco Switching/Routing :: ASA5505 / Network Design With Multiple Gateways?

Apr 11, 2013

remote location on MPLS circuit terminated on a Cisco router that has Internet connectivity through Central Site router.  We are installing a cable modem at the remote location that is to be used  as the Primary Internet Connection but still be able to use Internet through MPLS if the cable Internet goes down.  We want the failover/fallback to be handled automatically.
We have an ASA5505 for the cable Internet which then feeds into the ISPs modem. 
At first I was thinking about getting a module for the remote router so the cable Internet could be terminated on the remote router as well but that introduces a single point of failure.  I would also like to firewall both the MPLS and the cable Internet but if I do so on the ASA there is another single point of failure.

Protocols / Routing :: Connect Two Asterisk Server On A HP Pro Curve 2626 Switch

Apr 11, 2013

I am trying to connect two Asterisk Server (with DHCP server enabled on both) on a HP Pro Curve 2626 switch. Server A has IP address and Server B has IP address I created a two new VLAN on switch, VLAN2 for network and VLAN3 for network. I put the command "ip routing" on the switch. My goal is to be able to ping ip address from PC 1(VLAN2) to PC 2(VLAN3) and vice versa... I'm not sure what I am missing... By the way, there is NO ROUTER involved on this set up. I tried to Google and it says HP ProCurve 2626 is a Layer 3 switch so IP routing should be possible.

Protocols / Routing :: Linksys E1000 Router Failed To Connect To Internet

Dec 14, 2011

I've got a problem with my Linksys E1000 router. When I bought it, it worked without trouble. Setup was easy and straight forward and I was able to connect all my wireless devices (2 latops, a mobile) without any problem. Then, after two months or so, I noticed the laptops were losing internet connection (or not finding the wireless network on start up). Rebooting the router seemed to work the first couple of times to restore the wireless connections, but after a few more days, the wireless network either shows up and the devices are unable to connect to it OR the wireless network does not appear in the network list. However, the wired connection to my desktop PC via ethernet cable has no issues at all. My conclusion is that these wireless routers (E1000) have a defect in the radio card.

It says local access only. However in other countries (IM in NZ) it does connect to internet. It does work when I use an Ethernet cable between my router and the laptop. The second issue is with my other laptop. A HP Pavillion DV-4 windows vista home premium service pack 2. I manage to get wireless access to the internet but every couple of minutes the connections drops and starts again by itself�. After 1-2 min approx�. it is getting pretty annoying!I don�t think it is the routher as I also have an XBOX 360 connectet to the internet usign the same device and works absolutely fine!

Two Gateways On One Server

Jun 2, 2012

I have a milestone VMS (video management system) server running on a customers site. The server has two network cards. eth0 has a static IP, mask, gateway (the gateway is a firewall connected to the internet via an eircom modem in bridged mode) eth1 has a static IP, mask gateway all the cameras and related equipment are in the range ~ 20 Customers network users what to view the VMS via an application which needs to run on their PC and connect to the VMS server on, The customer has given me a gateway address of However when I use this gateway address in the default gateway of eth1 I loose internet access on the server because the server can not resolve the DNS address. The cusotmers users can see the VMS and the monitoring station can see the VMS via a VPN. However I need internet access otherwise Teamviewer will not work and I can not access the server for configuration and maintenance remotely. Is there some other way I can implant the customers gateway so they have access but I still have internet on the server.

Two Gateways On One Network?

Jul 25, 2012

I've got a network with the following address and subnet mask:


The original gateway that we had on the network is at:


This gateway is a Netgear VPN firewall and it also has a bit of port forwarding going on to a couple of servers on the network.We've now had a new line put in and we have to use different hardware on that line so in order to phase that in, I've set this up as a new gateway at:


Internally, the clients and servers are quite happy with this and will happily use the new line.Problem arises when users connect via VPN to the OLD gateway (I haven't got VPN set up on the new one yet). Users can still connect to the VPN but can't see any machine that is using the new gateway.How can I get around that? Does the old gateway need a static route?
