Connectivity issues

Avi Bar Ilan

Hi Guys

i have a very strange issue with my XG firewall.

i have 4 vlans and 1 ISP connection.

every few days, i find that connectivity is somehow faulty.

isp connection is stable but machines on (for example) clients vlan cannot get connectivity to nowhere.

i can ping the default gateway, but no more than that.

the firewall is online, but it is somewhat in a decreased functionality

these are example screenshots from a vm on the clients vlan...

ping to GW on the client vlan - OK

ping to GW on the servers vlan - OK

ping to a resource inside the servers vlan - FAIL

ping to 1.1.1.1 - FAIL

this happens every few days

please help

    Hi

    as for your first question, yes - shown in my screenshot.

    static routes have not been touched. when i do ipconfig /release + renew the client connectivity is fully restored including internal and external.

    if this was an issue with static routes - ipconfig /release + renew would have no effect.

    switch configuration is fine - we didnt have these issues before switching from fortigate to sophos.  

    traceroute when experiencing the issue looks like this:
