Hi,

what is the default gateway of the extreme L3 switch? I think it should be the pix in your setup.

Hi,

It seems to me some arp issue. May be PIX is proxy arping for your default gateway as well.

try "sysopt noproxyarp inside"

Thanks

My pix inside ip is 10.0.0.11 /16

My L3 extreme Switch is 10.0.100.1 /16

When i point my Web server Default gateway to PIX inside then browsing is fine , email is ok but

when i point my Web server default gateway to L3 switch (which all are in Same VLAN) no internet no email......

I feel there is some comapatibility issue between cisco and Extreme network .... and i need to do something on PIX or L3 switch any suggestions..

Hi,

maybe you could enable logging and see what the error messages are.

To enable logging to a syslog server:

logging host inside

logging trap debug

logging on

(ps, free syslog server available at: http://www.kiwisyslog.com/)

I would also like to repeat my previous question:

what is the default gateway of the Extreme Switch?

Kind Regards,

Tom

Hi,

did you try to configure the syslog logging? The logging should tell you what is going wrong.
