I'm having an odd problem, that probably has a simple solution, but just can't seem to figure it out. I've setup a VLAN on a Cisco SG300-20 managed switch (in layer 3 mode) with an ID of 90. I've assigned an IP network to the VLAN and machines on the...

I setup a new VLAN on my switch and I cannot access the internet from it. As far as I can tell all the routing information is correct. Machines on the VLAN can access the VLAN's gateway, my switch's IP address, and my router's IP address. They just c...

I have a Cisco 1941 ISR and a SG300-20 switch in my home lab with several VLAN's. I have a web server and an FTP server that normally can be accessed from the outside world, however, currently, my FTP server cannot get past my router. My network layo...

Just double checked and yes, the firewall is disabled my testing machine. I'm also trying to ping a printer on VLAN 90 as well. I can ping it from the switch and machines on VLAN 90, but like my other tests I cannot ping it from machines outside of V...

Thanks, that was it. Knew I was missing something obvious. I removed the access-group from my WAN link and so I wasn't thinking about ACLs used for NATing.

Sorry for the delayed response. Yes, there are no access-lists for 8 or 9. I noticed this before, but my web server (ip nat inside source list 8 pool web) does not have an access-list and I can communicate with it from the outside world without a pro...

I really don't like that router, most of the configuration is not available to you, and talking to Comcast is a nightmare. I ended up buying a Cisco 1941 to have a proper router and switch. When I setup the 1941 and SG300 I still had a similar proble...
