The routing isn't the problem.

Local gateway           eth0 10.6.1.1 ppp0 192.168.127.2
Remote gateway  eth0 10.1.1.6 ppp0 192.168.127.1

Local routes add -net 10.1.0.0/16 gw 192.168.127.1

traceroute from local gateway to 10.1.1.1 gets as far as 192.168.127.1 and
stops

If you say ip_forward is enabled then either there is a routing problem
or some firewall issue.
