ping breaks
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

Code:
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
Code:
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 
192.168.50.0/24 via 10.200.14.254 dev eth0 
192.168.151.0/24 via 10.200.14.254 dev eth0 
10.1.10.0/24 via 10.200.14.254 dev eth0 
10.200.17.0/24 via 10.200.14.254 dev eth0 
10.200.16.0/24 via 10.200.14.254 dev eth0 
131.11.3.0/24 via 10.200.14.254 dev eth0 
192.168.155.0/24 via 10.200.14.254 dev eth0 
10.200.14.0/24 dev eth0  proto kernel  scope link  src 10.200.14.11 
192.168.152.0/24 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

Code:
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
Code:
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
