I have moved a few Linux/apache servers to a new office.
New Comcast business 50/10 circuit, new L3 switch (of which I am not using any Layer 3 features) and a Sonicwall firewall.
In the old office, had unmanaged switches with the Sonicwall and the Linux/Apache servers running fine.
Now I have a manager L3 switch (only 1 vlan, Sonicwall and webservers are all in, same network 192.168.5.x), the new Comcast circuit and the ole' faithful Sonicwall.
Now the websites are not accessible on the internet.
Worked with Sonicwall tech support for 4+ hrs and he cleaned up the Sonicwall. that a software engineer (owner of the Linux/apache server went crazy with address objects and NAT policies - aka didn't know what he was doing and didn't tell anyone). Sonicwall, ok'd by tech, latest firmware, pretty good shape.
Now that leaves the L3 HP switch I put in place and the new comcast circuit.
The Sonicwall tech wants me to look into the MTU of the Comcast circuit to see if that is the issue.
I showed him the dumbed down L3 switch (everything in 1 vlan, on the same network) and he said the Sonicwall wouldn't care about that.
Side note, bought the L3 HP switch to do some future separating of groups and routing vlans to servers based on mac. Driven by the software guys. Lots of work there. anyway, the switch is sort of dumb right now.
Everything is fine on the network, except these websites that are now not accessible on the public internet.
Any ideas?
- could it be my L3 swtich, misconfigured in its dumbed down state?
- could it be a unique MTU size for this business class internet pipe?
- could it be an internal DNS issue, routing requests properly to the webserver (VM is hosting many websites via subdomains tc.comopany.com, tc2.company.com, etc.
- or is it the Linux/apache web server issue?
Thanks for any ideas....
