ASUS router Virtual Private Networking FAQ

This document includes information which may prove useful if you have an ASUS router and want to set up Virtual Private Networking (VPN).

*** WORK IN PROGRESS ***

If you have tried and succeed, or failed, to get VPN working with an ASUS router then please read this thread on ADSLGuide.

Whilst I am waiting for you all to supply me with accounts of your exploits with VPN and the ASUS router, there are a few points that are worth making:-

  1. Some forms of VPN like IPsec rely on packet types other than TCP and UDP; these will not work with the router in NAT mode since the router will only forward TCP and UDP packets.
  2. However, it appears that, in bridged mode, the router will not allow packets other that TCP, UDP and ICMP to pass through, if you have enabled IP Filter - to protect the router, say.
  3. If you wish to run VPN software that uses packet types other than TCP and UDP - in bridged mode, of course - then you can disable the router configuration by http and telnet instead of using IP Filter.
