SNS version 4.8.19 LTSB bug fixes

System

Filter - NAT

Support reference TAC-1565

In some cases, competing access to the cache would prevent a filter rule from being correctly applied. This issue has been fixed.

Dashboard

Support reference TAC-1460

The link that provides access to license details from the dashboard is operational once again.

GRE tunnels - Maximum Segment Size (MSS) value

Support reference TAC-1214

The firewall now correctly takes into account the MSS value of TCP packets that pass through a GRE tunnel configured with the command:

sysctl -w net.inet.tcp.mssdflt=<value>.

Storage

Support reference TAC-1167

The presence of a defective SD/microSD card no longer prevents the firewall from starting.

Static multicast routing

Support reference TAC-1462

Static multicast routing traffic sent from a bridge is now correctly received by interfaces outside the bridge.

Network - igc-based interfaces

Support references TAC-1559 - TAC-817

When a firewall interface that is based on the igc driver, and forced to a speed other than 2.5 Gbit/s, connects to a compatible device with throughput of 2.5 Gbit/s, the negotiation of the link at 2.5 Gbit/s will no longer be wrongly activated.

SSL certificates

Support reference TAC-1725

When a user authenticates with an SNS firewall using a certificate with TLS 1.2, this no longer causes an SSL protocol error with certain web browsers
