Firewall Rule Problems

[lordwarlock]

Hello,

i got some Problems with opnSense 17.1.5. Firewall Rules stop working after some time. To solve these issue i need to reboot the Firewall. Inbound NATed Connections and Outbound connections are affected.

As an example, there is a NAT Rule for inbound SNMP Traffic to my MailGateway. After a reboot everything is workling for some hours, then it stops - without any Changes in the Config i made.

I tried reinstalling and importing the Config, with no success.

It is an Installation on VMware ESXi 6.0 - the NICs are vmnet3

Can anyone help me?

Cheers,
Stefan

Hi Stefan

I have the same problem with Portforwarding and FW Rules. I can only restart the package filter service. How can i create a cron job who restart the service every night?

Best regards,

Flavio

PS: I know, it's only a workaround!

Hi lordwarlock,

Have you tried E1000 NICs under ESXI 6.0?  I am running E1000 NICs under ESXi 6.0 Build 5224934 with no dramas.  I was actually thinking about rebuilding OPNsense with VMXNET3 NICs, but have not got around to it.
