Hi Wireshark Folks,

The below query is not Wireshark specific, just a basic networking topic.
Pls hit delete if you dont care to read more.

I pose this query to this forum just because the collection of talent here should vindicate or refute my own sanity.

pls consider this network topology?

a site has a T1 to the cloud. following that T1 into the domain, we first encounter the T1 router, then on to a firewall, and arriving finally at a 10/100 Mbps switch where its distributed to internal users.

our access to the cloud has been degraded so we look for reasons why?

we find that the firewall is configured on both input/output sides to be 10 Mbps, half duplex.

AFAIK, upgrading the firewall interfaces to 100 Mpbs/FDx would increase the throughput by 10 times (ideally) and enable bidirectional traffic (as opposed to limiting to a single direction at once).

am i missing something obvious here? is there any reason a 10 Mbps/HDx link is better than 100Mbps/FDx ??

tia, jackc...




T1 speed is on the order of 1.5 Mbits/sec .....
