[Openswan Users] Need a VDSL2 modem known to work with Openswan

[Durwin]

I had a successfully working Openswan VPN using a qwest zyxel q100. 
After an 'upgrade' to Actiontec C1000A, my vpn stopped working.  It
establishes a tunnel but no traffic passes through.  Manual on the Actiontec C1000A
'says' it has ipsec passthrough, but after a lot of troubleshooting I've
been unable to get traffic through.

So my question is, is any one using a VDLS2 modem with PPPoE and
Openswan successfully?

Thank you,

Durwin
