Hi. I have problem in following scenario: 3 routers A, B, C: router A: eth0--> DSL ( public IP ) eth1 --> 192.168.0.1 ( local network ) routing table A: 83.x.x.x/29 dev eth0 proto kernel scope link src 83.x.x.x 192.168.5.0/24 via 192.168.0.8 dev eth1 192.168.4.0/24 via 192.168.0.8 dev eth1 192.168.3.0/24 via 192.168.0.8 dev eth1 192.168.2.0/24 via 192.168.0.8 dev eth1 192.168.1.0/24 via 192.168.0.8 dev eth1 192.168.0.0/24 dev eth1 proto kernel scope link src 192.168.0.1 127.0.0.0/8 dev lo scope link default via 83.x.x.x dev eth0 router B: eth0 --> 192.168.0.8 ( direct RJ45 connection to router A ) ath0 --> 192.168.3.1 ( wireless AP -- only for bridging with router C ). ath1 --> 192.168.1.1 ( wireless AP, for clients ) ath2 --> 192.168.2.1 ( wireless AP, for clients ) routing table B: 192.168.5.0/24 via 192.168.3.2 dev ath0 192.168.4.0/24 via 192.168.3.2 dev ath0 192.168.3.0/24 dev ath0 proto kernel scope link src 192.168.3.1 192.168.2.0/24 dev ath1 proto kernel scope link src 192.168.2.1 192.168.1.0/24 dev ath2 proto kernel scope link src 192.168.1.1 192.168.0.0/24 dev eth0 proto kernel scope link src 192.168.0.8 127.0.0.0/8 dev lo scope link default via 192.168.0.1 dev eth0 router C: eth0 --> 192.168.5.1 ( RJ45 connection for clients ) ath0 --> 192.168.3.2 ( wireless STATION -- bridges with router B ) ath1 --> 192.168.4.1 ( wireless AP, for clients ) routing table C: 192.168.5.0/24 dev eth0 proto kernel scope link src 192.168.5.1 192.168.4.0/24 dev ath1 proto kernel scope link src 192.168.4.1 192.168.3.0/24 dev ath0 proto kernel scope link src 192.168.3.2 192.168.0.0/24 via 192.168.3.1 dev ath0 127.0.0.0/8 dev lo scope link default via 192.168.3.1 dev ath0 THE PROBLEM: On first look all is fine but when I try to download http://the.earth.li/~sgtatham/putty/latest/x86/putty.exe on router C, connection freezes after receiving some kilobytes ( random ). The same file is downloadble on router A and B with no problems. This link http://kernel.org/pub/linux/kernel/v2.6/linux-2.6.22.6.tar.bz2 and many others are downloadble on on all routers A, B,C with no problem. It seems that some files freeze connection when sources by router C, but on A and B cause no problems.
