  Hello

  is it possible to access the RDC to two XP systems, with two different port for the DRC, behind a router with a single public IP address?

  Please note this ia a small home network without any parameters of the field. I use IP to access DRC.

  You comments are appreciated.

• Configure the router WRT54G with the PUBLIC IP address and use the DHCP protocol for internal computers

  Hello

  I have a service online Internet with 5 public IP addresses.

  The router and the AP are connected to a switch.

  I would like to set up a WRT54G Router with a public IP address and use DHCP (with private ip address) for the computers that will connect to the AP.

  That the AP is connected to the switch, it is possible that the other wired computers that are connected to the same switch can get an IP from the DHCP?

  Thanks in advance

  In this case, the routing is automatic.

  WRT54G configuration:

  WAN:

  Internet connection: static IP address

  IP address: 180.X. X 170

  Subnet mask: 255.255.255.248

  Gateway: 180.x.x.x (Ex: 180.x.x.1)

  DNS: servers your ISP DNS

  LAN:

  The IP address of the router: 10.10.10.1

  DHCP range: 10.10.10.100 of-online 10.10.10.200

• Deployment of ESA without public IP address

  Hello Experts,

  I want to know that if I deploy ESA in my network without public IP address with a config on the SAA as if is there any traffic to port 25, then transmits to the ESA to the Exchange.

  I published the public IP address of my firewall in the MX record.

  In this scenario, there will be no problem for the ESA to determine the reputation of the sender when you receive an email?

  And if ESA is not able to determine the reputation of the sender, then, what is the best way to deploy the ESA without using a public IP address.

  I know that 99% of the ESA facilities use a private IP address on the public static listener with NAT on the firewall in front of the ESA. There is nothing wrong with that. Just think that get translated here. This is the destination IP address of the request that comes from the internet and ESA can still see the IP address of the sender. Only your internal mail server does not see the sender-original INVESTIGATION period. But there's nothing in general not as SPAM-check is done, when the mail strikes the internal server.

• Site to Site VPN between ISR4331(Data Center) and 25 branches with RV042 and dynamic public IP address

  Hi, we just got router ISR4331. We will use this router to our datacenter as pummel hub. Not to mention that it will be the static IP address. Our goal is to connect 30 small offices to the Datacenter by VPN site-to-site. All of our offices a RV042 router and DSL connection, so dynamic public IP. How to accomplish this task. Before the VPN connection is stable and the need not to configure tunnels frequently.

• Could not ping router RV042G public Internet address when it is after spending a SG200-08

  I use the optical fiber Singtel broadband server. I installed a SG200-08 for UNTAG VLAN to port 2 and connect the port to port RV042G WAN 1. It works very well with a public IP address. Access to Internet is very well to router LAN ports.

  However, I try ping on the public IP address of RV042G of the internet, I could not reach him. Everything what I'm missing in configuration SG200-08?

  Hello

  I don'i heard the switch block ICMP traffic as it has layer 2 switch, can you please check if the Ping on the interface of the router WAN is activate--> firewall--> WAN ping of uncheck block

• The router RSV4000 does support multiple public IP addresses

  I have a client who has a RSV4000 router. The customer also bought a block of 5 usable public IP addresses. I need to be able to assign these public IP addresses for printers, either by configuring a static IP address on each printer directly or through mapping of intellectual property or any other method. Made support for RSV4000 using several treats public IP and if so what configuration is required in the router for printers to be seen by the outside world.

  Hi Winston,

  Thank you for posting. The functionality you need is one-to-one NAT, who does not have the RVS4000. Please watch the RV042 or RV220W for this feature.

• Is it posible to the public ip address of the default locking?

  Is it posible to block the public IP address by default on multiWAN routers?

  I have several RV016 with up to 4 30Mbps Internet VDSL lines each and using the latest firmware to load 50-200 customer balance.

  When it is used for navigation, some sites will have to lock public source IP of the customer (especially sites that requires a user authentication).

  From a server point of view, public IP address will be between public IPs provided by ISP, automatic suite 4 round robin load balancing strategy.

  As public IP, read by the server changed server reduced session, users will need to enter username and password again to connect.

  Is it posible to lock this public IP for awhile to idle? (he has been featured on my old router BeWAN LX400H as "timer LockSource IP")

  ebarriera,

  The RV016 has no functionality like timer LockSource IP unfortunately. It's a common problem with load in the Cisco Small Business routers and key balancing mainly "secure them" traffic like HTTPS and RDP. I would test balance HTTP traffic and link HTTPS traffic to a WAN port and see if you get decent results.

• Public IP address used internally on RV220W

  Hello

  I've finally set up our RV220W to serve our network of offices, using the following environment:

  WAN is set for a public IP (static configuration), while internal network consists of two VLANS.

  VLAN 1 is connected to the cable network and a SSID wireless, where DHCP is served by our server Windows SBS (192.168.15.x), and this VLAN is used only for our own office. VLAN 2 is connected to a second SSID wireless, where DHCP is served by the RV220W himself (192.168.17.x) and this VLAN is used for guests and visitors to our office.

  On a regular basis, we need to use a mobile device to access a test page of a development server on VLAN 1, and the router is configured to redirect the connections on a specific port on the public IP address to our development server.

  For VLAN 1, I solved this by substituting the DNS for the host name of this test page to use the local IP address of the development server.

  However, for VLAN 2, there is no way to access this test page.

  Is there a way I can configure the router to redirect connections, either replace the internal DNS for the test on the development server page is also accessible from 2 VLAN (network comments/visitor)?

  Thanks for any help.

• RV220W - multiple public IP addresses

  All, morning

  I am setting up this new router from a client. I'm running on a question that I can't make it work. I was wondering if anyone would be able to help. They use IP addresses public 5. Currently the wan port on the router est.66 and I have all ports forwarded to the correct internal IP. It works very well. However, I need parts before else public IP (e.g. internal:.67) to IP address So far, I was able to achieve through the TAR one-to-one feature. It allows me to forward a port from a public IP address to a private IP address. However, I need to redirect ports 3 or 4 by public IP address to one address only internal. Anyone know what I'm doing wrong here? This router does not support this feature?

  Thank you

  David Rhea

  Hello David,.

  How weird to put in place... but the nat from one to the other is the first step that you do. Once you transfer a port using nat one by one, and then you create an access rule. Create an ACL rule allowing traffic between wan and lan, what service/port you transfer, always allowm, fix ip source, destination ip, it's that you transfer the port too you would change the destination of the internet to others and then you should be able to fill the void of what another public address you are wanting to use. The test blank must be labelled internet destination ip:.

  I hope that helps you out.

  Thank you

• Numbering of the SIP Client IP addresses to public IP addresses

  Hello

  We are developing a new video network with VCS control and 2 highways of VCS. 1 expressway stressed the public internet address face and 2nd Expressway face partner network.

  Requirement: Internal SIP endpoint need dial IP address public (via Highway 1) and the IP address of the partner (via Highway 2). VCS control configured mode "calls to unknown IP address" to "Indirect".

  The two highways set up for 'Request to the unknown IP' mode to 'lead '.

  There is research on the VCS control rules to find the IP address.

  Priority 1 for IP address via 1st Highway

  Priority 2 for Ip address of partner via Highway 2.

  The two numbering IP addresses work, but component partner / IP address takes about 38 Sec to finish for the configuration of the call.

  When I look at the history of calls on the VCS control, I can see even for the search for the IP address of partners, 1 internet search Expressway and could not reach the IP address and then start to search on the highway of VCS partner and find the Ip address, like that it takes more time to complete the call.

  Sometimes, it is time and couldn't make a call of IP address to the IP address of the partner.

  is he kind, we can minismise the time for setting up call for the IP address of the partner numbering.

  Kind regards

  Chris

  Chris,

  try to disable SIP UDP on both motorways as this should reduce the appeal of 30 seconds preparation time.

  Hope this helps,

• EX90 two autonomous with the public IP address can make video calls among them self on the Internet or not?

  Dear expert;

  I am very new to VCS and TP Cisco.

  We implement now presence Cisco TV with VCS - C, VCS-E TMS, TCS, MCUS and endpoints with Jabber in a single edit.

  and in another configuration CUCM 10.5, UCCX 10.5 IM & P, Jabber with some 10 officers.

  Now the question is in our building on the 2nd floor we have an EX90 and on the 5th floor an EX90 and on local network, we can make video calls using the IP address.

  In the same way is it possible to make a video call between 2 devices EX90 (both have public IP) present in a location different in the same city on the Internet without the participation of VCS - C and VCS-E.

  It's the client request :)

  Concerning

  Paiva

  Yes, but leaving these systems outside in nature with public IP addresses, leaving you are vulnerable to a number of questions. See for example http://www.videonationsltd.co.uk/2014/11/h-323-cisco-spam-calls/

  https://supportforums.Cisco.com/discussion/12340591/nuisance-h323-calls-SX20

  The offers above with H.323 calls, in addition to this, you will encounter similar problems using SIP where the systems will be analyzed by tools such as SIPVicious
