Routers / Switches :: Linksys E3000 Router Will Not Forward Port 443

Dec 20, 2011

I attached an Iomego Home Media network hard drive to my Linksys E3000 router (via ethernet cable). Before setting up the remote access on the Iomega, I forwarded the ports that it wanted (443 and 21) to the static IP of the Iomega. I checked to see that they were open using and they were both open. After setting up the remote access on the Iomega, the 443 port closed and I cant even get into the "manage storage device" page for the Iomega. Iomega uses TZo for the domain names. They tell me that the association is made between the name and my public IP address. My router is out of warranty since Sept, so Linksys wont give me the time of day. I contacted my ISP and while they block a couple of ports, 443 is not one of them.I've installed the latest firmware (1.0.04 - Build 6). Reset and rebooted numerous times, Port 443 remains closed.

Cisco Switches :: ESW 520 24-Port Switch With POE Not Working?

Oct 16, 2011

We just purchased 8 managed switches POE to swap out our existing in preparation for our new phone system.  We installed them all after configuring with static IP.  Deployed... and all but two work fine. Any tips for troubleshooting why two of them do not work?  There are a couple other switches in the building.   Could it be that a switch "upstream" from the two non-functioning switches is causing an issue?  If so, how do I find out?  When we put back the two "dumb" switches all was fine.

Cisco Switches :: Configure SRW248G4 Switch Through Console Port?

Jun 2, 2013

I want to configure my SRW248G4 switch thru console port. Unfortunately in this switch there is no RJ45 console port input, I can only see cosole port that is look like RS232 input. I bought two standard cisco console cables that have one end with db9 and one with RJ45.

Now I have and idea to put one end of one cable (db9) to switch, and one end (db9) of second cable in my computer (COM input/output)
I need to connect two RJ45 together - this is not a problem, I know how to do this. Here is the question :I know how pinout in my computer look like but i can't find pinout of console port in my SRW248G4. There is many pictures in Internet, for many Cisco devices but this isn't working. Maybe in LINKSYS pinout look different ?

I have done some testing through Wireshark and there are absolutely no reports / logs.We have some real issues with this switch and it’s hard to believe that this is a Cisco Product,

Routers / Switches :: Still Not Able To Telnet / SSH To Switch?

Mar 14, 2011

I can telnet to switch from checkpoint firewall access port and from switch directly. I can ping/traceroute successfully to the switch. Access-lists 14 & 15 are allowing the traffic I want. The router on the other side of the FW has 2 static routes and a default static route set up.

Here is some of the config from my switch:service tcp-keepalives-in

service tcp-keepalives-out

service timestamps debug datetime msec localtime show-timezone

service timestamps log datetime msec localtime show-timezone

service password-encryptionhostname xxxxx

enable secret xxxxxx

username xxxxxxxx password xxxxxxxip domain-name xx.xx.netaaa new-model

aaa authentication login default local enable line none[code].....

Not sure of checkpoint firewall config....I have run wireshark when trying to telnet and I get no syn-ack back from remote switch. Just 3 consecutive syn attempts.I have some switches I can connect to and they go right through the 3 way TCP handshake and I cannot find any differences in the configs between the successful connections and the unsuccessful connections.

Is there a way to view the MAC table showing which MAC address is plugged into which port on the switch?  I have been fighting with the menu and the gui for a while now and do not see this anywhere.
