Hello, I want to connect multiple DSL connections on a Linux box the issue I have is that both of the DSL are from the same provider so both of them give me the same remote gateway, is there a way for this to work?? Is there a place where I can read about this ?? Thanks a lot for your help

There you will learn tht the fact that both providers have the same default gateway is totally immaterial. -Tom -- Tom Eastep \ Nothing is foolproof to a sufficiently talented fool Shoreline, \ http://shorewall.net Washington USA \ teastep@shorewall.net PGP Public Key \ https://lists.shorewall.net/teastep.pgp.key

If your DSL "modems" are configured in bridge mode and your internet interfaces are just ethernet interfaces (ethX) then there are some considerations. Most important of these is that your ISP''s router MUST ACCEPT GRATUITOUS ARP -- if it doesn''t, then you won''t be able to get this to work for the first N minutes (hours) after you reboot (N determined by how often your ISP''s router refreshes it''s ARP cache). A couple of hints: a) Don''t set ''logmartians'' on your internet interfaces because martians are unavoidable. b) You must be running Shorewall 3.0 and you must set arp_ignore=1 on both interfaces. c) In /etc/shorewall/start, you should include this command for each of your internet interfaces (ethX): arping -U -c 2 -I ethX <IP address of ethX> For more information about ''arping'' and ''arping'' packages, see http://www.shorewall.net/ProxyARP.htm. d) Proxy ARP won''t work without considerable extra work. -Tom -- Tom Eastep \ Nothing is foolproof to a sufficiently talented fool Shoreline, \ http://shorewall.net Washington USA \ teastep@shorewall.net PGP Public Key \ https://lists.shorewall.net/teastep.pgp.key
Actualy the connection is done using 2 ppp interfaces
But my doubt is this
Link encap:Point-to-Point Protocol
inet addr:201.155.70.252 P-t-P:148.223.255.127
Mask:255.255.255.255
UP POINTOPOINT RUNNING NOARP MULTICAST MTU:1492 Metric:1
RX packets:1557795 errors:0 dropped:0 overruns:0 frame:0
TX packets:1855822 errors:0 dropped:0 overruns:0 carrier:0
collisions:0 txqueuelen:3
RX bytes:607985821 (579.8 Mb) TX bytes:877870506 (837.2 Mb)
Both interfaces give me the same ptp address, and on the other hand im using
openswan to make a vpn ..
Thanks ..

Actually, that isn''t totally true. If your DSL "modems" are
configured in
bridge mode and your internet interfaces are just ethernet interfaces (ethX)
then there are some considerations. Most important of these is that your
ISP''s router MUST ACCEPT GRATUITOUS ARP -- if it doesn''t, then
you won''t be
able to get this to work for the first N minutes (hours) after you reboot (N
determined by how often your ISP''s router refreshes it''s ARP
cache).
A couple of hints:
a) Don''t set ''logmartians'' on your internet
interfaces because martians are
unavoidable.
b) You must be running Shorewall 3.0 and you must set arp_ignore=1 on both
interfaces.
c) In /etc/shorewall/start, you should include this command for each of your
internet interfaces (ethX):
arping -U -c 2 -I ethX <IP address of ethX>
For more information about ''arping'' and
''arping'' packages, see
http://www.shorewall.net/ProxyARP.htm.
d) Proxy ARP won''t work without considerable extra work.
