Objective

Computers that use Mac OS connected to RV0xx VPN routers may experience a significant slowdown and have problems with DNS resolution if their Internet Service Provider (ISP) does not route IPv6 DNS queries. The solution is to disable IPv6 on Mac OS itself as the Safari and Apple applications do not have a separate process to disable IPv6.

This article explains how to disable IPv6 on Macs connected to RV016, RV042, RV042G and RV082 VPN Routers.

Applicable Devices

• RV016

• RV042

• RV042G

• RV082

Software Version

• v4.2.1.02

Step 5. On the Ethernet page, click Advanced.
