Hello,
I'm runing colinux as an Internet router. I defined two nics (eth0 as TAP to link the Windows system and a WINPCAP to link the the Internet) In front of this I already have a DSL modem which does NAT :
Internet <------> DSL Modem <--192.168.0.0/24--> WINPCAP <------> coLinux <--192.168.34.0/24--> TAP <-------> Windows
And it's working fine so far except I noticed something really weird. The coLinux system is running maintenance jobs also and one of them does backups using FTP. And when coLinux starts to upload files to Internet, all network traffic seems to be stuck (ie it's impossible to browse Internet from Windows). There is no problem at all during parallel downloads. Uploading trought FTP using the Windows system gives the same issue. Of course the problem disappears when I connect the Windows system to the DSL Modem. I don't know if the issue is related to coLinux or iptables and I don't know what to do more to investigate.
I have another question related to my setup. I would like to know which solution is better : WINPCAP or TAP + Windows native bridging ? I tried both solutions but this didn't solve my problem.
I'm running coLinux dev (latest snapshot) ,debian sid, arno firewall rules.
Thanks for input,
Regards,
Jerome
