Hi all,

 In my n/w iam using iptables firewall in my gateway and now the problem
is iam able to use that machine as a default gateway for all the
windows machines in my network but i cannot even ping the
gateway/firewall from linux machine.
 the strange thing is if i ping a client linux machine from the firewall
it pings and from then onwards i can ping/use the gateway to browse the
net even from a linux machine.
 every time if i want to use that g/w from a linux  machine i had to
ping the client machine from the firewall to enable it.
 iam using iptables 1.2.5/Redhat Linux 7.3
 

 can any body help me out to resolve this strange problem

the rules i cannot ping it.
moreover the problem is only with the linux boxes ,all my windows
machines happily use the gateway.
