You want to route via the gateway 212.199.26.28 on interface eth1,
but previously you declared 212.199.26.28 as being accessible via
interface eth0. You should try just:
route add -net 192.168.1.0 netmask 255.255.255.0 gw 212.199.26.28
or, a little redundant:
route add -net 192.168.1.0 netmask 255.255.255.0 gw 212.199.26.28 dev eth0

HTH,

i tried that as well still says network unreachble.

Can you ping 212.199.26.28 ? The gateway machine must be reachable
before you set up this routing rule.

To use an IP as a gateway, it needs to be covered by a -host or -net LAN
route (with gw 0.0.0.0). The only route you have to public IP
212.199.26.28 is a "non-local" route (gw 172.23.128.1) on a different
interface (eth0). Since you have no direct route to 212.199.26.28 (with
gw 0.0.0.0) on any interface, you cannot use it as a gateway period.

The only route you appear to have on eth1 is what I think is bogus IP
range that Windows uses if it has no IP and cannot find a DHCP server
(IANA blackhole).

Perhaps if you made an ascii art (fixed font) diagram of your network, it
would be easier for someone to come up with a proper routing solution.

but i ping 212.199.26.28 from my client pc.

what i about the route
172.23.128.0 0.0.0.0 255.255.224.0 U 0 0 0
eth0
212.199.26.28 172.23.128.1 255.255.255.255 UGH 0 0 0
eth0

and network topolgy can be found at:
http://www.iglu.org.il/amit/cable/

i've made progress,
i placed
iptables --table nat --append POSTROUTING --out-interface ppp0 -j
MASQUERADE
iptables --append FORWARD --in-interface eth1 -j ACCEPT

(the change is that instead eth0 in postrouting i've typed ppp0) i also
removed gatewaydev=ppp0 from network file.

i can now ping the gateway 212.199.26.106 and can also recieve web
pages.
BUT the i cannot recieve all web pages, and while some come up they
come up veeeery slooooowly, and others do not come up at all.
