1720 VPN and Winproxy behind 826, VPN drop outs

DSL into 826. Winproxy and 1720 into 826.

1. Can the 826 prevent VPN traffic while allowing web traffic to flow thru Proxy?

2. Does the Proxy server setting in IE connection override default gateway IP?

The problem is that VPN clients have Default GW as IP to 1720 and proxy server WinProxy IP. Connections are unstable w/ no correlations. Web and VPN can both work or either or none.

Re: 1720 VPN and Winproxy behind 826, VPN drop outs

You could block all "non-proxy" access through the router by creating an access list doing so. The only IP you would allow through would be the proxy server's requests and then, only it's source address and proxy ports if you want to be very specific. As I understand it, when you configure a proxy setting in a browser, any request the browser makes (http, https, ftp, etc.) will be directed to only the proxy address and the default gateway will never be used. The PC would only use the default gateway for any non-browser client applications (VPN client software, telnet, ping, smtp, pop3, etc.) Of course, if you blocked all "non-proxy" traffic as I suggested, none of these applications wil work unless you modify your access list to allow them.
