We recommend that you update your SNS firewalls to a version with maintenance to guarantee the protection of your infrastructure.
SNS 3.7.3 LTSB bug fixes
Network
Static multicast routing
Support reference 70211
A restriction on queue size management in multicast static routing would cause the loss of multicast packets. The size of these queues can now be configured using the command:
CONFIG SMCROUTING UPDATE UpcallQueueLimit = <queue_nb_packets>
For more information on this command, please refer to the CLI SERVERD Commands Reference Guide.
System
USB over Ethernet modem
Support reference 65697
When restarting a U30S or SN200 firewall, the detection of the USB over Ethernet modem would take too long and no IP address would be assigned to the modem. Network services on the firewall therefore needed to be manually rerun (ennetwork command). This anomaly has been fixed.
SNMP
Support reference 70258
Querying OIDs that correspond to the firewall's network interfaces no longer causes the firewall's SNMP server to consume too much memory.
Captive portal - Sponsorship
Support reference 70007
An anomaly in the management of sponsorship requests would wrongly cause the detection of a brute force attack and block the requester. This anomaly has been fixed.
VPN IPsec
Support references 71401 - 70250
The use of the AES-GCM algorithm by one of the peers of the IPsec policy no longer causes packet loss during the phase when the destination firewall decrypts the traffic .
Intrusion prevention
SNMP
Support reference 68686
Enabling intrusion prevention analysis on the SNMP protocol no longer causes the excessive consumption of processing resources on the firewall, nor slows down all network traffic passing through this firewall.
