Cisco WAN :: 2800 Setup Router To Resolve Both Internal / External DNS Requests

Jun 3, 2012

I have a 2800 with one Gigabit interface connection to our Lan and the other interface connected to the internet with a public IP address. Now I'd like to setup the router to resolve both internal and external DNS requests. Thus requests like www.google.co.za and LocalLanPcName should be resolved to their public and private IP's respectively. [code] When I ping any name the only DNS server that is ever queried is 192.168.1.200 (it does resolve internal name correctly though).

None of the other servers are attempted to resolve the name. It does not matter if I specify a FQDN or not.
 
How do I setup the router so that my internal resolution is handled by 192.168.1.200 and .201, while external resolution is handled by 41.160.36 and .37. Or alternatively, how do I configure it to at least try all 4 specified name-servers for resolution, and not fail after trying the first one unsuccessfully.

Linksys E3000 - Internal / External LAN Firewall Setup?

Oct 20, 2012

I have Astaro UTM running on an old computer as my only firewall right now. The Astaro also serves as my DHCP server. My Wifi is provided by a Linksys E3000 running DD-WRT software. NAT/SPI are disabled on the E3000, and it forwards DHCP requests to the Astaro. All my network clients connect via wifi/ethernet to the E3000.

All clients --> E3000 (no firewall) --> Astaro --> www

I am considering setting up my own personal cloud server using a Synology NAS that I can access remotely. I would also like to remotely access my Surveillance DVR. I would like to access them via VPN or portforwarding. I do not want to use DMZ.

I would like to utilize the SPI firewall on the E3000 to provide an extra layer of defense. I would like the NAS and the DVR to be on an external LAN between the Astaro and the E3000...and all other clients being on an internal LAN behind the E3000. I have the necessary switches/cables to make this work.

My question is...How do I configure the E3000? Can I have both the internal and external LANs on the same subnet? Do I have to use the NAT on the E3000? I'd rather not...since that will render the Astaro's reporting functions rather worthless.

I would like the Astaro to remain the only DHCP server. I would like all internal LAN clients to be able to reach out to the external LAN/WAN...but the external LAN should not be able to reach into the Internal.

Cisco Firewall :: ASA 5520 - Unable To Resolve External Hostname Internally

Jul 1, 2012

I am working on adding a mapping to our external address for our mail server - let's call it mail.example.com
 
I would like to be able to access mail.example.com internally for our user's smartphones - if they access our company WiFi they are not able to get mail using the mail.example.com as the server name in their phone setups.  However, once they leave the office and use any other WiFi it works fine. Also, I am unable to ping that address from any internal device.  I believe also this is the reason Exchange accounts do not work on our site to site VPN connections.
 
I have a ASA 5520 and work primarily in the ASDM 6.4 to do configurations in the main office and have 5510 in our site to site connections.

D-Link DIR-655 :: How To Forward Requests To External Http-Proxy

Nov 23, 2011

Goal: To forward requests over port 80 from my LAN to an external server on a specific port, that is I would like to forward all requests over http to an external proxy.

I know that this can be done with IP-Tables, but I would like to do the same thing with my D-Link. I have looked at Advanced --> Routing, but that seems to be specifically for inbound requests. I want to do this for outbound requests. This can be achieved with the D-Link DIR-655?

Cisco Firewall :: 8023 / External Access To Internal Router Via ASA

Dec 31, 2012

I am aware that we can allow external admins to telnet over a custom port to the internal router. Even i was allowed to connect to a remote router via the remote firewall. The way i was accessing the router is by telnet to the remote ASA address on port 8023.I am not sure how exactly we can configure this on a ASA.

Cisco :: 2800 Enable SNMP Discovery Through External Interface

May 28, 2012

I'm trying to add some 2800 series routers to our monitoring environment, but I can't get them discovered.
 
On the Mgmt Server I need to go through a "discovery" process to add the 2800 to the system. For this I target the internal interface ( i) but the discovery fails. I'm assuming the packets are getting dropped on the outside interface (e). I know SNMP is set up correctly and works as I had PRTG installed on a local box (p) for testing purposes.
 
The intention is to do the data gathering via a proxy agent (p), so enableing SNMP on the outside interface is not going to do me any good.What do I need to do to let those discovery packets pass through? At least temporarily?

Cisco WAN :: 2600 - External To Internal IP NAT?

Jun 10, 2013

I have a 2600 I am trying to setup for educational use. 
 
My Cable ISP has issued me 5 routable IP's through their SMC modem 86.28.12.226-229.  The SMC modem is .225.  Currently the internal network can get out through .229 as expected but nothing outside (tcp 80 to web server) can get through.  When I assigned the ip's to e0/1 as secondarr I could get it to route from the inside network (so hitting .226 80 went to the correct place) but it still didn't work from the outside - plus I read that wasn't a great way to do it anyway.

External IP To Internal Device?

Sep 22, 2012

I have a checkpoint Safe@Office 500 firewall router, connected to adsl via another adsl device in bridged mode.We needed to assign an external IP to a device behind the firewall.We contacted the ISP, and now they have assigned an additional IP to our adsl account.I have read from the documentation that:"NAT can be defined automatically via the network object (Node, Network or Address Range). When you define NAT via the network object, rules are automatically added to the Address Translation Rule Base"....so I add the object, with the external IP given to us by our ISP, and the wizard simply complains that the IP address is invalid.My thoughts are that the router does not know about the additional IP provided by our ISP. If so, how do I tell the router that there are other IP addresses available to use? I have rebooted the router, and no luck.

Cisco Routers :: QuickVPN Setup On RV120W Without Changing Internal Setup

Nov 8, 2011

Is there a way to set up Quick VPN on the RV120W without changing the internal subnet? I have just taken over responsibility for a network and I don't know all of the nooks and crannies yet, so I'd rather not change the internal sub net. I've tried setting up a user then changing the LAN settings afterward, but it automatically removed the VPN user when I did so.

Cisco Wireless :: 2504 - Using Both External And Internal DHCP On WLC

Nov 25, 2012

I am wondering if the folowing is a valid configuration:

WLC2504
AP2600
 
I need 3 SSID/VLAN, 1 for corporate devices, 1 for coporate smartphones, 1 for guest.

Port 1 on the 2504 should be used for management and corporate devices and connect to the corp network. Port 2 is for smartphones/guest and will be connected to a Cisco ASA 5515 that is connected to a second ISP.
 
Corp devices should get IP from an Windows DHCP. Smartphones/guest should get IP from the WLC. Is this possilbe? I read this in a document "To use the WLC as a dhcp, you need to enable DHCP proxy as it is required." Some how I am imagining that this will mess with the Windows DHCP. Is it better to use the ASA as DHCP for smartphones/guest?

Cisco WAN :: ASA 5505 - Assign External IP To Internal Server?

The first one I use to provide internet access to my office. The other two I'm going to use for the following: I'm going to deploy a server in internal network which must have 2 external ips on his network interface (& one internal ip on the second,but that's ok: I cannot put an extra network switch before asa & plug this server there: this server is virtual & is on esxi host in internal network. External ips must be assigned to servers' interfacw,bot just forwarded there (ms direct access requirement).

My current config:

Slow To Access Internal Sites Via External IP

Jul 17, 2012

Our secondary site accesses the internal intranet via a link, which is basically:

[URL] where externalip is the IP address of my router.

* This used to work fine before we migrated from ADSL (6mb up / 0.5mb down) to Fibre(70mb / 20mb) *

Internally, I access the same link, but via [URL] Internally it loads in 2 seconds, externally it is taking 68seconds(ish)..

I can't work it out, the fibre shouldave made things loads quicker but is infact very slow. I'm wondering if something network wise is going on.

The intranet is a php intranet sitting on apache, and using postgresql as the database. Other pages load fine, this specific index.php page does quite a lot of DB connections and so on, but as I say before, it worked fine before the migration.

Netgear Router / Setup An Internal Network In One Room Of A Building?

May 1, 2012

internet provided to whole building with connections in every room -> personal router in my room -> my PCs, Macs & printer, how to set up my computers so that they can share files with each other and print to my network printer, but without being susceptible to being accessed from other computers in the building? I have my own netgear router. But at the moment, my shared folders are accessible by everyone in the building, so is my printer If I set all the computers to automatically set ip by DHCP, they can access the net, but everyone in the building can access them (and my printer which requires a manual ip doesnt work). If I set all the computers to manual addresses (e.g. 192.168.1.14 ... 192.168.1.15 ... 192.168.1.16 etc.) they work with each other, the printer works, its secure, but I can't access the internet!Is there a way to for example have my own internal network with manual ip addresses, while also being able to connect to the net?

Cisco WAN :: WRVS4400N - External Web Server Can't Connect To Internal SQL Database

Jul 4, 2011

I have a hosted web server that has a website on it that needs to connect back to a database within our internal network. We have a Cisco WRVS4400N Wireless Router with 2 VLANS. VLAN 1 goes to a Watchguard Firebox which is connected to our internal network. VLAN 2 goues to our classroom network.
 
Our database is on VLAN 1. I have opened port 1433 on the Watchguard to allow SQL traffic from our Web Server. I can telnet from my workstation on VLAN 1 to the Web Server over port 1433, so I know the Web Server is not blocking anything. When I try to telnet from the Web Server to our Public IP address over port 1433, it fails.
 
I believe I have the firewall on the Cisco WRVS4400N off, so it shouldn't be blocking any traffic, but for the life of me I can't get this to work. I have been working on this for two days, and I NEED it to work. This was working up until last week, then it quit working. I am the only person making changes to our network, and there were no changes made during that time.

Cisco Firewall :: ASA 5505 Internal Address To Forward From External One

May 30, 2013

I have an old ASA 5505, and I'm having some trouble with Nat Hairpinning. I've done this with other firewalls before and I am having no luck now. I have an internal address that I wish to forward from an external address- so if someone goes to 123.456.789.012:3456 then it will forward to 192.168.1.244:92 (All numbers are arbitrary here- only for illustration). I have and Access Rule and NAT and PAT set up so that I can get in if I originate from outside the LAN. What I am trying to do is to have this work from inside the LAN as well- so that if I am at my desk, and I connect a device and type in 123.456.789.012:3456, it will deliver the content at 192.168.1.244:92. The problem I am having is that it just isn't working, and I cannot figure out why- When I started here, there was an address configured to work this way, and it still works- I just cannot find what is different between what I am doing and what the person who configured it did.
