    Dear Team,

    We have two offices at 1 floor. both are connected with uplink of their switch.

    We are facing latency or packet drop issue at second office. I am not sure why facing such kind of issues but it may be some packets or request redirected to the firewall. Due to this our switch traffic get jam & we are facing network congestion issue

    My concern is only that request will move to the firewall which want internet access, apart from that all LAN traffic will use another gateway to local transfer or communication purpose.

    For your kind information I am giving you Network Infra.

    1 office :- 40 Users, 1 Firewall, Squid Proxy Server, 3 Switches
    2 office :- 20 Users, 2 switches
    Up-link from office 1 to Office 2

    1) What traffic flow is having latency issues?

    2) Are the two offices on the same subnet or different ones?

    If the affected traffic is within the same subnet that is having latency issues, your firewall has nothing to do with this as the traffic is not being routed. The only time a firewall may have an affect on layer 2 (non routed) traffic is if the firewall is set up in transparent mode doing layer 2 filtering; even then it's not definite as it depends on where on the network the firewall is inserted.
