Cisco WAN :: How To NAT Static IPs To Servers On SRP541W
Apr 15, 2012
We have 2 servers currently and are adding one next month. All need to be accessible using a different web address. We have setup a records for the 2 existing servers but cannot get NAT to work properly. We have a block of 5 IP's from FIOS. x.x.x.146-150 and have tried using 146 and 150 as the main WAN static IP with no success in getting the other address to communicate to the corresponding server.
What we need...
Server @ address 192.168.2.2 - SBS Server, standard SBS ports - currently working via port forwarding with WAN static of .150
Server @ address 192.168.2.3 - RDP, HTTP, HTTPS, and others. Some ports are the same as SBS. Trying to NAT .149 to this server.
Server @ address 192.168.2.4 - RDP, HTTP, HTTPS, and others. Some ports are the same as SBS. Trying to NAT .148 to this server.
All servers are on VLAN 1 which has a static IP of 192.168.2.1. DHCP is controlled by SBS.

I am trying to configure a Cisco 871 router.There are 3 servers on my network that need static public IPs but also still need to communicate on the local network.I have given my WAN interface the first IP in the block and set up PAT for the rest of the computers on the network with that IP which is working fine. Next I set up static NAT rules for the servers translating 3 of the remaining public IPs to the internal addresses of the servers.I can access those servers internally using the public IPs but not from outside the network. A traceroute from outside the network gets dropped when it gets to my ISP.I've never configured more than one static ip for a network before and i know i've just missed a step here. Do I also need to use static routes? Will that update the next hop's routing table? Do I need to make an ACL to permit any host to the servers? If so, do I use the internal or external address? [code]

I got the charge of a ASA 5510 running with 8.3(1) version.Found that this is simple config with Patting for inside host and couple of Static Nat for web servers and FTP server as well.
There is lots of other configuration being done,I assume for the purpose of just R&D by the previous administrator.I need to understand if the following Nat statements holding any relevance?
Where we are running Only NETWORK_OBJ_192.168.0.0/23 subnet at inside and there is no other subnet defined in rest of the statements.i.e 10.0.0.0/27 and 192.168.1.128/27 doesn't exist at all.

I am trying to build a site-to-site VPN between cisco 1811W at a main office and SRP541W at a remote office.
I already have the configuration for the 1811W through SMD, but can't install the SDM on the SRP541W.
Does the SRP541 is compatible with SDM; and if not is there any other GUI to configure a VPN tunnel on SRP541.

i have recently successfully configured an IPSEC VPN from a SRP541 to our Zyxel Zywall 70 (main site).
I can ping all devices on the remote Site except the Cisco-Router!I tried to disable tohefirewall and did set "Anonymous Internet Requests" to "disabled".But still no ping (and no web management) over the VPN possible.
I must admit i am totally new to Cisco devices (up to now, we used only Zyxel) - so is guess it must be something very basic i am missing.

I just bought the SRP541, and it has the old firmware. I downloaded the new firmware, yet I cannot figure out how to install it.

Recently we have purchased a few SRP541W for our small branch office VPN sites. While working with the config I have discoved that when trying to create a IPSec VPN policy, I am limited to only one "remote network" entry. This is typically not how VPN tunnels are bulit. We generally put the following remote networks in the tunnel. How do I open a BUG ticket with Cisco and ask that they change the code?

I'm running FW 1.02.01 (23) and I'm having problems with the DNS proxy. I have DNS Proxy enabled for my DHCP server on the router and I have my dns server programmed into the global dns location. I cannot ping any DNS names for my IPSEC VPN tunnel.

I have an SRP541W with two ADSL modems attached to it. Both are running bridged mode with PPPoE connections to two different ISPs, (TPG and Telstra Business Direct). The TPG connection is far cheaper, and has a much higher download limit. Sadly, if I leave the router in "load Balance" mode for the WAN, it "prefers" the Tesltra connection because it's faster. I want downloads for movies/music, Youtube, Internet Radio, etc, to go through the TPG connection. Is it possible to do this in the router, or would I need to set up a proxy server, (or some other external device/application)?

We purchased a Cisco 541w router for one of our customers.
The main reason was to provide them with 3g backup solution for their business.
In order for the router to recognise the 3G router the firmware was upgraded SRP540_1.02.01_023_081211_1136.
We arrived on site last night to do the install but couldn't make any changes to the already configured router. Every time we attempted add a vlan or adjust the dhcp scope the router would return "The values are invalid".
Worked at this for over 1 hour and then decided to factory reset the router to see if that would revert the router to use the original firmware.
This didn't revert to the previous firmware but we magically could now make network changes without problem.
So everything was good, we reconfigured the router, tested 3G and failed the wan1 interface back and forth and the customer was very happy.
Customer arrived onsite this morning and the router was running on 3G. Every 8 - 10 minutes it was attempting a failover between connections.
I decided to turn off the failover for the time being and investigate further but yet again i was back to "the values are invalid"
We've had to pull the router as the customer is about 2hours away and revert back to their BT router.
Found this document for another SRP model - A warning message may appear in the Basic Wireless Settings screen with the text “The values are invalid” when modifying the wireless profile. Set the SRP 521W to its default setting (CSCtd49614).

Will firmware SRP540_1.2.4_003_011112_1847 released only 2 days ago cure the problem?

I'm running FW 1.2.4 and how to setup Remote Web Access over my IPSEC vpn tunnel. I would like to be able to remotely access these routers and make configuration changes from my main office but I cannot seem to figure out how to get it to work. If I try to access the internal router IP from across the VPN, I cannot. My VPN tunnel is up and operational and I can ping various devices across the tunnel but I cannot access the web management of the router.

I'm wondering if there is a possibility to get my homepage provider's custom dynamic DNS service working on my Cisco SRP541W Router as I'd not like to be forced to sign up for either DynDNS or TZO which are available through the web frontend.

I've configured an srp541w router for a customer and successfully configured an IPSEC VPN connection with a Netopia router at a satellite office for the customer.
I cannot seem to find a way to configure either a PPTP VPN connection or QuickVPN connection for remote users. I did read something that stated that the router will only support either a site-to-site VPN or a QuickVPN connection, but not both at the same time.

I am using an SRP541W router and i am trying to configure 2 vlans, each one to use its own Wan:Here are the dhcprules and vlans:As can be seen, each one has its own wan interface.
Vlans:As can be seen, each vlan is using its own ports and dhcp rule, so, now they should be separate.
Both Wans are connected: So now (at least as i see things) the two vlans are separate and using different Wan. But the reality is different, everything is going out using Wan1.Also in the Interface Info you can see that the 2 vlans are listed under the Wan1.
The rest of router setting are default.

We have an SRP541W on which I thought I had disabled DHCP, its turns out that in fact I haven't. After seaching again for the DHCP on/off funtion I found it under the Vlan settings (Wierd place to put it I thought).
The Router has a static ip address on the LAN side of 192.168.1.254 and is connected to a Cisco 2700 series on the WAN side. Our network DHCP is served by an SBS 2011 server hence my reason to switch off DHCP on the router. However when I select Static IP address from the Address Type in the VLAN settings and try and save the changes I get an error that is IP Address / Subnet Mask value is illegal. Great but why when the router has and IP address assigned and the subnet mask is set do I get this error. On the VLAN settings page there is no option to set an IP Address

I used to have a DLINK router which covered my whole house with its Wifi signal. After upgrading to the SRP541W router, only the very close vicinity of the router has any acceptable level of signal to use devices. I seriously need to improve WIFI range to accomodate my small business. I asked the Live chat technician and the answer was "This device does not support external antennae" and then silence. Okay it is not supported but what I am looking for is a solution, not a dead end.
For example, is there a cisco repeater/extender that I could deploy that works with the SRP541W router? Any experience adding one long cable and putting one antenna at a different location of the house?

Unfortunately, it does not appear as if the SRP500 series will allow you to create an ipsec policy where the local or remote traffic selection is 0.0.0.0/0.0.0.0. It wants a specific network. I have a scenario where I want to send all traffic over the vpn tunnel.
Is there a workaround to this or a special way to input "ANY" as the remote network?

I have a problem connecting SRP541W to my ISP (L2TP). Connection is established, but default routing table is wrong: instead of gateway I see Server IP: [code]
In similar situations other users of my ISP with Cisco routers (IOS) solved this problem by adding command no peer neighbor-route but i can't do it through the WEBgui...

I am new to VLANs although I generally understand the concept. I have a small office with 25 desktop/laptops and 15 VoIP phones connected with a SG200-50 switch and on Port 1 I have the Cisco SRP541W router for DHCP and Internet access. My goal is simple: 1) Segregate the VoIP phones (voice) from the computers (data) and 2) Prioritize the VoIP phones traffic.
I believe this can be accomplished by setting up a second VLAN and maybe a third (if the default should not be used) and then identifying those ports as Voice VLAN ports. I guess I just need to know how to flag each interface and each port so that they all can talk to the router on Port 1 yet the voice and data will be in different broadcast domains. Also, do I need a management VLAN??
Is this setup correct? VLAN 1 - default (data) Port 1 (Trunk) (Tagged)Port 2 - 30 (Access) (Untagged)VLAN 2 - voice Port 1 (Trunk) (Tagged)Port 31 - 48 (Access) (Untagged) What should the interface settings be on each port (General, Access or Trunk)? What should the port VLAN membership be on each port (Tagged or Untagged)??

We are planning to split the Private servers from the DMZ Servers and configure an additional Interface and segment for this purpose.
Private Servers Segment: 192.168.4.0/24 (there is no DHCP all servers' IPs are statically configured)
DMZ Segment: 192.168.3.0/24 (This is a future deployment)
LAN Segment: 172.17.0.0/16
Both, Private Servers and DMZ Servers are in a collocation as well as the ASA5520. There are multiple Branch offices that uses subnets within the 172.17.0.0/16 Network and they are connected to the ASA5520 via Metro-E.
I do not know if this is possible but what I want to do is this:
In order to avoid the change of internal DNS records I want to mask the DMZ servers with a Private Server IP when a Private server or LAN host wants to access it like this:
The FTP server in the DMZ has the IP address: 192.168.3.100. But when a PC from the LAN wants to reach the FTP server it should points to its old IP: 192.168.4.100. This way the PC sends a packet to the ftp.corporate.net (192.168.4.100) the ASA recieves the packet and translate it to the (192.168.3.100) and send it out through the DMZ Interface.
Also if the Private Servers wants to reach the same FTP the ASA will act like a proxy-ARP and send the paquet to the DMZ by means of the translation of the IP.

Today I installed the 1.0.2.6 Firmware on a RV180W. I only have now two problems regarding the Static DHCP support in the GUI.
1. Via the Networking > LAN (Local Network) > Static DHCP I have no buttons to Add a new static Lease.
2. Via the Networking > LAN (Local Network) > DHCP Lease Clients I can thick a Lease and click on Make Static IP. The result is an error: Operation failed.

I've set up port forwarding from an external port (9000) to an internal port (80) on our SRP541W, and for some reason, it's not working externally. If I access the public address from within the internal network, it works properly.

Ideally i want these to both use the same external IP address, so should i configure a dynamic policy NAT rule for these two servers?

I have a server subnet that for the most part needs to be able to access the internet for patches, updates, etc. My SysAd wants 2 of the servers to not have access. The server subnet is attached to a 3750 and connects to an ASA to reach the outside world. Would it be better to setup an ACL on the SVI of the server subnet or on the outbound direction of the outside interface on the ASA.
