I've just purchased 2 switches SG100-24 and use fiber cable to connect these switch together. I plugged cable in module MGBSX1 and then put it into miniGBIC uplink port but despite trying many times, also rebooted devices, I still not make these uplink ports up. how can I bring them up?

I'm having this really weird issue with my DIR-655 revB. I have some port forwarding rules set up and externally they work fine. However, if I try connecting to my IP address using those same ports from a computer within my LAN, it won't connect.
Externally, I can ping my WAN address and connect through forwarded ports. No problems. Internally, pinging my WAN address apparently works (just now is the first time that's worked for me), however I can't access any of my computers using the WAN IP and port forwarded ports. I can access them by going directly to their hostnames or LAN IPs.
Things I've tried:
-Disabling/enabling firewalls on all computers involved
-Disabling/enabling QoS engine
-Disabling/enabling DNS relay
-Disabling/enabling Advanced DNS
-Adding custom nameservers from Google and Comodo
-Restarting computers
-Clearing DNS cache (I use a dynamic DNS name which works externally but not internally. This gets the correct IP internally and connecting directly to the IP doesn't work either.)
-Modifying the NAT Endpoint Filtering settings
I have an external DSL modem connected to the router using PPPoE if it matters.
The weird part is that it works externally but I've modified all of the values I can think of in the config with no luck. I upgraded to the DIR-655 from a DIR-615 which had all these settings in it and worked fine (until it started acting up which is why I replaced it).

I have looked up countless guides, and have done everything in them, I have a static IP, I used the gateway to create the port forwarding rule, AND opened the ports on the windows firewall.
Nothing works. The port remains closed, and I can't host games. My modem is an Ambit U10C037

First off, my router is a D-Link DIR-655, firmware v2.07. I'm trying to port forward port 25565.
My port forward settings are this:
However, when I use this open port checker, it claims that I don't have that port open. It looks like this, without the blurred out parts:
Added note: The way I want to use it is by my IP (xxx.xxx.xxx.154:25565). I have the software installed to do so (I'm using a minecraft server, connecting through minecraft), but I can't enter my IP in the IP address field, it says that it's out of the range of the LAN.
I have a linksys wrt54gs wireless router (working fine since last 3 years) which connects to the internet fine if there is no password set. However if i set WEP password to protect the wireless connection, i am not able to connect to the wireless connection. Everytime i enter the passphrase, when trying to connect to the wireless network, it refuses to accept the password. I have tried this with 2 laptops (both running windows 7) and both have same issue.

View 1 Replies View RelatedI have an SA 500 with the optional port configured as the DMZ. The LAN ports are running the 192 range and the DMZ is the 172 range.
I have seperate offices (A few hundred feet apart) that have been connected with 2 un managed switches up linked with a single wire. The 192 range stuff runs over this. I need to get the DMZ out to the second room and was asking about how to do this over the single up link and switches. (Trying not to run a second wire)
My lack of understanding had me draw up this diagram attached as a picture, to ask about. What it shows is me trying to get the DMZ through the up linked switches to the other room. I thought of using 2 routers, one on each end. I've been told this is incorrect and wont work.
Maybe a purchase of a second hardware and eliminate the switches? (up link the SA 500 to another device?) What should that device be?
I've got an SG300-10 connected back to back (trunked) with a Cisco 3560X switch, across a fibre link and am seeing some big inconsistencies in terms of unicast data transferred across the ports between them.
During a night time window of 4am - 6am I run backups which involves a large copy of files, that almost saturates a GigE link - we can see from the 3560X end that the link is running at a bit over 800MBit/sec of throughput, sustained. The duration of this transfer is consistent with the size of the files being transferred (ie just over an hour, and is what I'd expect for a data transfer of about that amount). Back-of-the-envelope calculations indicate that the 3560X is measuring this data throughput correctly.
However on the SG300 end of the link, which is also being polled by the same application (Cacti), I'm observing spikey counts of only around 20MBit/sec during that window. These counters are very obviously incorrect - there's a huge amount more data moving across the port than that. The incorrect calculations are showing on both the trunk port out of the SG300 (uplink) as well as the interface where the NAS is connected in (which is an access port).
Cacti is polling the OID: .1.3.6.1.2.1.2.2.1.16.57 which translates to IF-MIB::ifOutOctets.57 = Counter32.I'm running version 1.3.0.62 but this problem is not new to this release - previous releases and 1.2 based releases also had this problem.
It looks like multicast traffic may be being counted correctly (that's only a suspicion though), however what I am certain of is that there is a very large discrepancy with the unicast traffic counts.Is this OID the correct one to be using for this switch?

I have an existing company network on 192.168.111.0 and want to create a vlan on 192.168.1.1 that can talk to 192.168.111.0. I have enabled layer 3 routing on the switch via console and also provided the ip routing command. I have the following VLAN's:
VLAN1 - Default 192.168.111.0
VLAN2 - 192.168.1.0
I have enabled DNS and provided my two DNS servers 192.168.111.82 & 192.168.111.212. I have set the VLAN1 interface to 192.168.111.217 and VLAN2 interface to 192.168.1.1.
Ports FE1 - FE15 are set to access ports and assigned to VLAN1 (untagged)
Ports FE16 - FE24 are set to access ports and assigned to VLAN2 (untagged)
I have set a default route for the switch to 0.0.0.0 0.0.0.0 192.168.111.254 (Draytek 2600 router). I have connected a computer (A) to VLAN1 port FE3 and a computer (B) to VLAN2 port FE16.

Computer B can ping computer A and RDP onto computer A but does not have access to the company network i.e MDaemon, file server etc. It also cannot access the internet.

Im now in charge of a medium/big size network (around 1200 machines).I found some connection pattern that im not shoure if it is correct.I migth be wrong, but i think this kind of connection would cause a continue RSTP change of topology (confusing about the 'direction' of the route to take), so having some latency period (this pattern of connection can be repeated several times in the whole network).BTW, there is no special configuration in switch A for saiyng that port 50 is not being used as a uplink port.

View 6 Replies View RelatedAt our office we have a weird performance problem with the following switches and connectivity:
Internet |
SG300-24 (L3) core switch (in our server room)
|SG300-10P (L2) access swtich (in our meeting room) |
SG500-28P (L3) switch (in our meeting room)
We are building a new computer infrastructure that is connected to the the SG500-28P. As you can see above the SG500-28P in our meeting room has an uplink to the SG300-10P in the same meeting room. And again the SG300-10P has and uplink to the SG300-24 in our server room. From the server room, there is connectivity to internet. The network uses a multiple VLAN's and routeing between them. Bootom line is, the internet VLAN ID 10 is tagged to trunk ports and available on the SG500-28P. So client get connected straight into the internet based VLAN.
The performance on the SG500-28P switch itself from VLAN to VLAN is very fast. But... the uplink connection tot the internet and other VLAN's on the core switch are very and very slow! At least 10 times slower than normal. So if I plug a laptop in the SG500-28P and go from uplink to uplink, it is slow! But... when I connect the same laptop to the SG300-10P the connection with only one uplink it is fast. As if three switches is to much. I can't figure out why.
I have three switches:
primary - Cisco Catalyst 3750G-24TS-24
and two SG300-28
I need to apply uplinks as follows:
3750G-24TS-24 SFP (1) -> SG300-28 (first) mini-GBIC (1)3750G-24TS-24 SFP (2) -> SG300-28 (second) mini-GBIC (1)SG300-28 (first) mini-GBIC (2) -> SG300-28 (second) mini-GBIC (2)
I would like to know, What type of mini-GBIC and SFP and cable I should use for SX Multimode?What max speed rate I will get?
I implemented the 3560E switch, this one have two Giga bit ethernet/10-Gigabit Ethernet module slots. I used the Twin Gig Converter Modules and one SFP. All configuration was applied in the Ten Giga bit, however the interface giga bit ethernet is UP UP state and the Ten giga down down.
