Level 1

Hi Folks,

I'm cutting my teeth on cisco and am having some issues with intervlan routing. I have followed the vids and manuals but just can seem to get this working. I have the following network lab set up.

Vlan 10 = 10.70.1.9/24

Vlan 20 = 192.168.0.1/24

ME2400 firmware

ROM: Bootstrap program is ME340x boot loader

BOOTLDR: ME340x Boot Loader (ME340x-HBOOT-M) Version 12.2(35r)SE3, RELEASE SOFTWARE (fc1)

Switch uptime is 7 minutes

System returned to ROM by power-on

System image file is "flash:me340x-metroipaccessk9-mz.122-44.SE1.bin"

Running config :-

witch#sh run

Can anyone help me ?

Hello Scott,

you should consider that your hosts may have a SW FW running on them.

the fact that each host can ping the SVI of the other vlan is a proof that inter-vlan routing is working correcty.

Host to host communication involves possible network protection on end user devices.

For example windows running PCs show this kind of behaviour.

Hope to help

Giuseppe

Hi Giuseppe,

I can ping both hosts from the switch

Switch>en

Switch#ping 10.70.1.5

Type escape sequence to abort.

Sending 5, 100-byte ICMP Echos to 10.70.1.5, timeout is 2 seconds:

!!!!!

Success rate is 100 percent (5/5), round-trip min/avg/max = 1/4/9 ms

Switch#ping 192.168.0.5

Type escape sequence to abort.

Sending 5, 100-byte ICMP Echos to 192.168.0.5, timeout is 2 seconds:

!!!!!

Success

But cannot ping through the switch to each other. No SF FW in the picture...both hosts are vanilla installs with no FW or AV installed totally open machines. Weird ?

Scott

Hi Giuseppe,

You were right, out Symantec has the Smart firewall activated and was blocking pings from foreign networks (Was running hidden). I had the windows firewall switched off though.

Thanks for all your help.

Scott

Hello Scott,

I'm glad to know that my suggestion was helpful.

Best Regards

Giuseppe
