Download Firmware DrayTek Vigor 2820/n/V 3.3.4

Draytek released a new firmware for the Vigor 2820 series routers a few days ago. In this family include the Vigor 2820the Vigor 2820n and the Vigor 2820Vn† The previous version of the firmware is already eight months old and the list of changes and improvements is long.

New Features:

• Support NAT port trigger.
• Support WIMAX
• Support WCF (Commtouch solution)
• Support mOTP.
• Add IGMP V3.

improvement:

For Firewall

• Improved: Improve security when using PCI scan tool to scan TCP session.
• Fixed: WCF configurations might be erased after reboot.
• Corrected: a memory misbehave for WCF.
• Improved: firewall robustness.
• Improved: Add VLAN condition in firewall rule filter.

For VPN

• Improved: Apply “My WAN IP field” to IPSec NAT mode for CheckPoint router.
• Improved: Improve VPN interoperability with Cisco router.

For NAT

• Corrected: NAT mechanism can handle DNS packets
• Corrected: Connection failed with PPTP protocol when the VPN server is located behind NAT.

For ISDN

• Corrected: When WAN1 & WAN2 aren’t enabled, ISDN connection can’t be triggered by packets.
• Fixed: ISDN-TE incoming call makes FXS & ISDN Phone ringing. When FXS answers the call, ISDN Phone rings still.

For TR-069

• Corrected: TR-069 stun function cause incorrect socket behavior which may cause other function fail.
• Corrected: Https URL (without port number) setting in ACS Server URL field doesn’t work.

For USB

• Improved: Add samba server for user management
• Fixed: 3G code makes router booting failure
• Fixed: 3G modem unplug may cause buffer release error.
• Fixed: Problem of FTP, Samba service
• Corrected: SAMBA transfer problem.
• Corrected: Some problems occurred in USB Syslog.
• Corrected: The router will crash when using Mac OS X to access USB disk via Samba protocol.
• Corrected: USB Samba sharing not working properly with Total Commander.

For 3G

• Fixed: Dial-up failure caused by 3.5G disconnection on communication.

For WiMAX

• Improved: Set WAN2 MTU (for WiMAX: 1380, for other: 1442) in Quick Start Wizard.
• Fixed: L2TP flag is not cleared when changing WAN mode to WiMAX.
• Fixed: Set MTU value for WAN2 back to 1442 if WAN2 mode is changed from 4G to Ethernet or other mode.

For DNS

• Fixed: PC sends out AAAA query, but DNS server answers without AAAA type. It causes the transparent mode for AAAA type failed.

For Wireless

• Improved: Support inbound QoS for wireless client.

For VoIP

• Improved: Use telnet command to turn on/off intercom; intercom is for calls between phone1 and phone2.
• Improved: Disable intercom by default and provide a CLI command to enable intercom.
• Improved: Modify ZRTP retaining shared secret mechanism to not save data to flash.
• Improved: VOIP call status supports “call return” from ISDN-S0.

• Improved: Add protection for various calling cases when SIP buffers are insufficient.
• Improved: SIP registration via VPN tunnel.
• Improved: Add secure phone option switches to dial plan page.
• Improved: Add ISDN-S0 to support Call barring.
• Improved: Reduce web file memory usage.
• Improved: Modify the mechanism to handle SIP header named “MIME-version”.
• Improved: Improve call waiting function for SIP account assigned multiple ring ports (broadcast call) setting.
• Improved: Improve robustness for ZRTP protocol (for secure phone application).
• Improved: Improve interoperability with some SIP proxy server for registration expiry time.
• Improved: Improve interoperability with some SIP UA for SDP protocol.
• Improved: Support broadsoft server CLIR mode.
• Improved: Add loop detection for SIP protocol.
• Improved: Change WUI title from “interface” to “route” in DigitMap and Call Barring page.
• Fixed: a broadcast call waiting problem (ie more than 1 ring port is ticked for a SIP account)
• Fixed: MWI stutter dial tone error.
• Fixed: a call waiting bug.
• Fixed: Potential reboot error while using the telnet command of voip.
• Fixed: SIP account stops to do registration in some case.
• Fixed: If the block interface is ISDN, calls from ISDN-TE port still need to follow the call barring rules.
• Fixed: Control error for VoIP offnets to ISDN PIN code
• Fixed: Internal call failure.
• Corrected: VoIP call log display error when the call log exceeds 10.
• Corrected: a VOIP buffer leakage problem in registration with blank “domain”.
• Corrected: Several Call Transfer errors occurred and hang up all the phones at once.
• Corrected: The GPIO configuration(GPIO 3: FXS_ONHOOK_DET1;GPIO 7:INT of ISDN; GPIO 22:FXO_INT and SPI GPIO PIN)
• Corrected: a SRTP buffer leakage problem.
• Corrected: Add a configure flag to control the PSTN call ringing the FXS port, otherwise when you upgrade firmware from firmware 3.3.3, the PSTN loopthrough will fail to ring FXS port.
• Corrected: a VOIP STUN server doesn’t work with WAN2.
• Corrected: Error occurred in ISDN port hotline. The malfunctioning is caused due to incorrect channel-port mapping.
• Corrected: While using the Far East VoIP box with Vigor SIP ALG, mobile phone keeps ringing after VoIP call hang up.

• Corrected: VoIP driver error under stress test.
• Corrected: When SIP server uses dynamic domain name and changes the IP address, the SIP account registration will fail.
• Corrected: SIP server with early media will cause no ring back tone.
• Corrected: Correct the timing of flashing phone LED.
• Corrected: A workaround to solve the incident that Vigor2820Vn loaded 2820VSn’s config rebooted itself during boot up.
• Corrected: Not reject T.38 protocol cause the FAX operation failure. (T.38 will be supported in next version)
• Corrected: Memory leakage in SIP protocol for specific SIP server.
• Corrected: After finishing a VoIP call, the DECT phone will cause the router reboot for the echo canceler is not disabled.

For TR-069

• Corrected: TR-069 stun function causes incorrect socket behavior which may cause other function fail.
• Corrected: Https URL (without port number) setting in ACS Server URL field doesn’t work.
