Yes, I was successful actually :)
The configuraton was as follows(ip addresses changed to hide the box-- s/real.ip.address/192.168.1/g):
Co-located machine had 2 IP addresses assigned:
fxp0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
inet 192.168.1.11 netmask 0xffffffc0 broadcast 192.168.1.63

ether 00:02:b3:d1:c5:39
media: Ethernet autoselect (100baseTX <full-duplex>)
status: activeMachine at office had two bridge mode 1.5Mbit/256kbit ADSL connections(The IP addresses were just ifconfig'd on each NIC).

The co-lo machine's ppp.secret contains: #---start ppp.secret--- username_goes_here password_goes_here 10.60.50.6 #---end ppp.secret---
/etc/inetd.conf on the co-lo machine had the following lines added: #--start-- #incoming ppp ppp-in stream tcp nowait root /usr/sbin/ppp ppp -direct ppp-in #--end--

ppp on the office machine was started with: ppp -background multilink

Performance increase was about what I expected.. doing an FTP download we were seeing about 280kb/sec. Uploads were going at about 38kb/sec
Not too bad considering it was a quick and dirty job. I tried to get it going with UDP but it refused to
work for some reason. Perhaps MTU/MRU stuff could be tuned a bit more finely but in the end
it wasnt going to be quite fast enough for the client. He was hoping to see 45kb/sec for uploads.
Let me know how you go :)
ive cc'd this to [EMAIL PROTECTED] in the hope that it becomes useful to some one else also.
Mabye something a bit too obscure for the FAQ or Handbook.. let me know if im wrong :)

Subject: Using multilink ppp(or similar) over 2 bridge mode ADSL connections... From: [EMAIL PROTECTED] <mailto:[EMAIL PROTECTED]> (Shaun Dwyer) Newsgroups: freebsd.net Organization: TAC News Gateway Date: Jul 25 2003 09:12:53 Hi All,
Please include me in the to: line as I'm not subscribed to this list(Thanks!).
I have a project where I need to be able to use the full available bandwidth of 2x 1.5M/256k ADSL links. I will have a machine co-located at a local ISP shortly and hope to run a ppp(or other?) server on that machine, and make 2 connections to it from the home machine (one on each ADSL link). Has anyone done this before? any ideas as to the best way to achieve this? Secure data transmission is a must. I'm thinking that ipsec on the tunnel thats established would be sufficient.
This is more in an effort to gain full speed access to the machine terminating the remote end of the link. Access to the net via this multilink connection is not important.
TIA, -Shaun
