Hi Community expert,

We have issue when connected to FSASE VPN then no internet access at all.

Fortinet found the root cause which due to FSASE side had cached the Network ID and when user try reconnect back the VPN, due to different Network ID, it will block the internet connection.

Fortinet did not provide workaround for more than 12 days while it affecting our production.

We tried to disconnect Telemetry and VPN and reconnect back, but failed.

Any expert have home cook workaround on this since Fortinet is not helping?

Your kind insight will be really appreciated.

Thank You

Hi @yksoon

When you say internet does not work? is it happening to all user connecting to different POP?

Does ping to 8.8.8.8 also does not work or issue only with browsing?

Thanks, Salon

HI sjoshi,

You may check ticket (11986250) for more info with detailed discussion in ticket (11996986), finally workaround interim FortiClient installer provided after so many days. (After 10 days ++ production impact)

Fortinet internal initially mentioned it fixed at latest 7.4 version which require FSASE’s backend FortiEMS upgrade, but after further questions more regarding whether it really fixed, now Fortinet only tell us that actually the issue will only fix in 7.4.8 which only available on upcoming month.

Thus the initial requesting upgrade and fix is just “Fake” solution for that issue.

More info can ask Jonathan on what been discussed. Ticket (11996986)

By the way, this is not the first time we encounter things that Fortinet said fixed, but eventually we found out issue not fixed at all.
