Cisco Routers :: How Does Quality And Longevity Of SRP500 Series Compare To RV Series

May 27, 2012

My Draytek 2710 just dies after 2 years so I was looking for something a little more reliable and noticed the spec of the SRP527W-U.I take it with only one antenna and reading a couple of past discussions, the wireless will only manage n-lite as some people call it i.e. 150Mbps, and not the full 300? Oh, and are the ports still only 100M and not Gig?I know the 547 would tick both these boxes but we are talking twice the price.  How does the quality and logevity of the SRP500 series compare to the RV series (which would need an adsl modem) or the Linksys boxes?

Cisco Routers :: RV016 (Small Business) Does Not Answer To Incoming Ping

Dec 4, 2011

Cisco RV016 Small Business Router (firmware version . We have several old RV series Linksys, and the interface seem identical to this new Cisco version so it isnt difficult to have it configured. However, I am facing issues. I cannot ping from untrust to WAN IP of the router.  However pinging from trust to any IP is just fine.
I tried disabling firewall, I also created a firewall rule that allows all ICMP from ANY to ANY. I also tried All traffic from Any to Any. But still the WAN1 and WAN2 IP addresses (Multiple ISP) still does not reply to ICMP.

Cisco Routers :: Wag120n How ADSL Modem Handle Incoming Sip Calls

Feb 14, 2013

I have a Cisco wag120n adsl modem. I am setup with a SIP provider, so all my incoming and outgoing calls use SIP.So my question is, how does my ADSL modem handle incoming SIP calls,e.g the SIP call comes in and reaches my adsl modem. Then, how does the modem find the actual port that has my ATA adaptor (analog phone) or CME router attached  ? I know port forwarding would handle this, but I am not actually using any configured port forwarding rules.

Home Network :: Which Computers Is Running Skype Application That Will Answer Incoming Call

Feb 15, 2013

I have a standard ADSL modem which connects to the internet. On the inside I have a few computers within my LAN.when the modem receives an incoming request from the internet for a connection to one of my LAN computers e.g. a Skype incoming call, how does the modem know which port to forward that traffic to on my internal LAN? i.e. how does the modem know which of my computers is running the skype application that will answer the incoming call? I know port forwarding normally handles this sort of thing, but in my case, I am not using any configured port forwarding rules so how does the modem know where to forward skype traffic?

Cisco Firewall :: SA520 Blocking Incoming Calls?

Nov 8, 2012

I have an SA520 that is being used as a front end firewall.  Behind it I have an IP PBX.  The VOIP provides are registered and I can make outgoing calls.  However It appears that the SA520 is either blocking or not routing the calls.  I have opened the ports recommended by both the IP PBX and the VOIP provider.  What do I need to do to make incoming calls through the SA520?

Cisco Routers :: RV042G - Port Forwarding To 2 Different Destinations Based On Incoming Wan Port

Apr 22, 2013

how to: port forwarding to 2 different destinations based on incoming WAN port
The default HTTP service works fine: TCP80/80->
I have a couple of IP security camera's I'd like to be able to access remotely that also listen on port 80. I tried TCP & UDP 8009/8009-> without any luck. Not sure how to handle the port redirects on the RV042G? Seems simple and was on the Symantec, could be user training :-)
I was able to do port redirect with the Symantec Firewall I'm replacing.

Cisco Routers :: Route 2 Incoming IP-Addresses To WAN Port Of RV110W

Oct 12, 2011

Just  purchased a Cisco RV110W for our small business.  We were told this was  easy for us to use and secure enough for our small office and for our  travelling sales staff to access our website.
We  purchased 2 dedicated IP-addresses, for access to one  server, and for access to a second server (these  IP-Addresses given are just an example; not real). 
These come into the single RV110W WAN port.  The two servers are plugged into 2 of the 4 LAN ports. 
But  the WAN setup page only accepts one WAN IP-Address.  So when we put in, the outside world can HTTPS into one server, but we don't  know how to get them to HTTPS to the second server when the other staff  uses
In  summary, how to use the RV110W admin panel to forward the  HTTPS/SSL traffic from to one server (setup internally on, and the HTTPS/SSL traffic from to the other  server (setup internally on using the VLAN setup on this  router)?

Linksys E4500 - Can't Find An Open Incoming Port

Mar 1, 2013

Im using a Linksys E4500 wireless router behind a Motorola SB6121 modem. My OS is Windows 7 and it is fully up to date. In general my entire network is working well. Now I have purchased a new IP surveillance camera and need to forward a port to be able to have remote viewing of the camera. Mi ISP blocks quite a few inbound ports including 80 so I have been trying a lot of ports all over the map to find something that will allow inbound access.

After several hours, nothing I have tried works, using a couple of different port probes including one called CanYouSeeMe I always get a "timed out" message. I have disabled the firewall in the router and on the local computer and still no luck. This says to me that either Cox is blocking nearly all ports (doubtful) or the modem is blocking access to the router somehow.

The Surfboard modem doesn't have a built in router. Unfortunately I don't have an old working modem to put in the circuit.

I don't guess it matters but the camera is accessible from all other local computers on the LAN using its IP address with a port number appended (right now it's using 8000).

Port Forwarding Working For Incoming Traffic But Not Outgoing?

Feb 6, 2012

I have a licensing server. Other computers need to turn on a program, they send a message to the licensing server, and it responds that they have permission to run.Until today the licensing server was plugged into its own ethernet wall socket and configured with a static IP address. Today I put a router into that wall socket and now the server's plugged into the router.The router (WRT-54G) was set to the static IP - and now the internet on its network works. I set all ports to be forwarded to the server's internal IP address - and now my programs can detect and ping it. But now the server won't send back permissions to use licensed software, or even reply with a list of the software which it can license.

Linksys Wireless Router :: WRT54G Incoming Log Destination Port 520

Aug 8, 2012

my WRT54G has been configured to block any and all incoming connections.continue to have disabled all port forwarding, port triggering, the DMZ, and QoS, via the applicable tabs under the [Applications & Gaming] Panel. The WRT54G continues to be configured to operate as a Gateway.No static routes are defined. The routing table show four entries, none of which are remarkable or match in anyway the partial address identified above.So I am under the impression that my WRT54G should be ignoring everything from the WAN-side.Even pinging the WAN-side of my router from the outside internet times out.My WRT54G ver 6 is at firmware level 1.02.8, which, as far as I can tell is the latest issued by Cisco.I am completely perplexed how such a connection is being established, and do not know if it is or has the potential of causing any harm. My own research indicates port 520 is typically used for RIP protocol, but I have almost zero knowledge of such.

Cisco Routers :: RVS4000 QoS Configuration / Phone At Remote Site Drops Calls

We have an RVS4000 router at two ends of a VPN tunnel. The VPN tunnel is  working fine, however a phone at the remote site drops calls, even  though they sound clear and unblemished. I have set highest priority on  the port the phone is hooked up to at the remote site, and have set a  priority for upload traffic on both routers, but the phone stills drops  calls after 2 to 3 minutes.

Cisco Routers :: RV042 Hardware V 1.2 Firewall Is Blocking Some Incoming Mail

I have found a few articles and forums online about otherpeople having the same issue with the RV042 v1 randomly blocking, e-mail but no one ever has a solution to correct the issue.Some people have recommend to roll back to factory default and reconfigure the router as the config may by corrupt.

Cisco Routers :: RVS4000 Firewall Is Blocking Incoming Data To Ephemeral Ports

Apr 23, 2012

If I have the IP ACL firewall enabled in my RVS4000 I have trouble connecting to specific websites and also connecting to Apple's update servers.  The problem appears to be that the firewall is blocking incoming data to the ephemeral ports even when they are allowed in the firewall rules.  I've also tried port forwarding rules but the only thing that resolves the problem is to disable the firewall entirely, which is not the desired resolution.  The firmware version is 2.0.27.

Cisco VPN :: 876 - Connection Established From Firewall But No Ping Answer

Mar 18, 2013

We try to establish a Site-To-Site- IP Sec- connection between a Cisco 876 (local site) and a Check Point-firewall (remote site). The Cisco 876 is not directly connected to the internet, but is behind a DSL- Router with port-forwarding, forwarding ports 500 and 4500. The running config of the Cisco 876 is appended to this discussion thread. Unfortunately I get no output when debugging the connection with commands "debug crypto isakmp" and "debug crypto ipsec".

From the Checkpoint-firewall point of view the connection seems to establish, but there is no ping answer.

The server on the local site that should be reached from the network behind the Checkpoint-firewall has a routing entry "route -P add [inside ip-net remote] [inside ip local]" (see also appended running config for naming of ip- addresses). Establishing a Cisco VPN- Client connection to the same Cisco 876 router works fine.
