== DNS Spoofing when PPP is Down ==

====Issue Description====

When PPP is down (ie no internet connection) the router will answer DNS queries and answer with ~~it's~~ own IP. This means that the user will be taken to the ZyXELs own web interface when trying to access a website when the internet connection is down, this applies for http and https traffic. This is not a configurable option.

==HTTP & HTTPS Interception/spoofing (when router offline)==

====Issue Description====

If the router looses its internet connection (eg drops sync, drops ppp) then it will intercept web page requests and will forward them to itself. This is meant to be 'helpful' in that the router will then have a page telling the user that internet is down etc. However, as it also intercepts https traffic this will cause certificate warnings in the browser which will alarm and the user and is much less useful.

====Resolution====

Static routes can be added via the [[VMG1312:~~_Static_Routes~~|CLI]]. Alternatively you can use the ZyXEL as a bridge and perform PPPoE on your internal router/firewall device.

==Dropping PPP for 15-20 mins RESOLVED==

====Issue Description====

We are seeing some lines, when in router mode (ie plugged in to the phone line and used as the router) drop PPP and do not re-establish PPP for ~~15-20~~ minutes. This is very odd. AAISP are investigating this as a priority. A work around is to use a separate DSL modem and configure the ZyXEL as a PPPoE router. This is not ideal, do talk to staff about this.

*Setting the VMG to bridge mode and using a separate PPPoE router works fine.

Also see 'Web UI Hangs (Broken HTTP/1.1)' on this page.

When using the router's own wifi, viewing the web pages (http) is very slow. eg, 20 seconds to load the Wireless settings page. Switching to Wired the pages load as expected. Whilst the web UI is slow, telnet CLI and normal internet access is fine.

====Issue Description====

The QoS and traffic limiting features have the potential to be quite useful. However, the default QoS settings have problems if there is a large rsync (over ssh) upload in progress in that DNS queries time out. We have some QoS notes on [[~~ZyXEL_VMG1312~~-QoS]].
