Lan pc (192.168.16.0,192.192.192.0,192.192.2.0) use this as gateway.

RHEL Box with squid has 2 nic as follows

WAN
eth0 192.168.1.20
gw 192.168.1.1
dns isp dns

LAN
eth1 192.168.16.20

All users browse internet thru squid proxy it works fine, but when I amd unable to access isp (202.XXX.XXX.XXX)mail server thru remote destop and send or receive mails from isp mail server.

please let me know ho to configure directly access the isp mail server to send n receive mail as well as access thru remote desktop

thanks

How did your WAN interface become 192.168.1.20 ? The ISP is probably rejecting everything that comes from such an address. Before you spend time messing with mail servers and/or routers, first fix the WAN interface. In most cases, it should be assigned by a DHCP server. In /etc/sysconfig/network-scripts/ifcfg-eth0, there should be a line like
Start by making sure the ethernet is configured correctly.

Dear Mr Rod,

Thanks for your support, i have made mistake, the correct flow as follows:

Internet----Router---Squid----Client

-----------------------------------
router ip address=192.168.1.1

Squid eth0 IP=192.168.1.20
GW IP=192.168.1.1

eth1 IP=192.168.16.20
gw=nil

Remote & Routing Server IP=192.168.16.1

client ip address=192.168.16.XX
GW 192.168.16.1


Thanks

Your router interface to the Internet cannot use a local-only IP 192.168.xx.xx
