I have implemented advance routing fo load balancing and a script for and
fail over on a Linux machine which run squid and dansguardian for proxying,
i have three interfaces on this machine which are
10.201.108.254 eth1 external interface connected to service provider
10.201.109.254 eth2 external interface connected to service provider
10.200.14.11 eth0 Internal interface for users.
Routing List
192.101.5.0/26 via 10.200.14.254 dev eth0
10.1.45.0/24 via 10.200.14.254 dev eth0
192.168.100.0/24 via 10.200.14.254 dev eth0
10.201.108.0/24 dev eth1 proto kernel scope link src 10.201.108.11
10.201.14.0/24 dev eth3 proto kernel scope link src 10.201.14.11
10.201.109.0/24 dev eth2 proto kernel scope link src 10.201.109.11
192.168.65.0/24 via 10.200.14.254 dev eth0

10.203.0.0/24 via 10.200.14.254 dev eth0
172.25.0.0/16 via 10.200.14.254 dev eth0
10.100.0.0/16 via 10.200.14.254 dev eth0
192.172.0.0/16 via 10.200.14.254 dev eth0
169.254.0.0/16 dev eth3 scope link
10.200.0.0/16 via 10.200.14.254 dev eth0
default
nexthop via 10.201.108.254 dev eth1 weight 2
nexthop via 10.201.109.254 dev eth2 weight 1
I have added static routes for LAN users which are
#LOCAL NETWORKS
any net 192.168.151.0/24 gw 10.200.14.254 dev eth0
any net 192.168.50.0/24 gw 10.200.14.254 dev eth0
any net 192.168.152.0/24 gw 10.200.14.254 dev eth0
any net 192.168.155.0/24 gw 10.200.14.254 dev eth0
any net 192.168.65.0/24 gw 10.200.14.254 dev eth0
any net 192.172.0.0/16 gw 10.200.14.254 dev eth0
Problem is that when i ping internal interface that is 10.200.14.11 which is
assigned on eth0, the ping breaks too much due to which browsing gets slow
when internet traffic load is high on proxy server then ping breaks too much
on internal interface, i have checked the network on layer-2 switches and
layer-3 firewalls which are fine changed network cables also changed network
interface on proxy server still ping is breaking, i dont understand wts the
reason traffice flow is Users -> Firewall (gateway) -> Proxy Server ->
Router -> service provider
any help will b highly appreciated
