Hello friends,
I have two Cisco routers 2501
between them there are dedicate line with two
modems . There are three networks
172.20..x.x ---router-line(172.30.x.x)-router-172.22.x.x
I cant ping from 172.22. subnet to some servers into
172.20. subnet

Thank you

Check your routing, each server should have its default gateway set to its local router.
Also each router needs to have a route entry for the remote subnet via the next hop IP address at the far end of the line.

Thank you

Yes , I have default gateway in this server
cisco pix firewall and if i made in such server gateway Cisco router 172.20.1.254 it works but I cant do such thing
because internet we receive throught pix not from router

How to summ up or join Cisco 2501 and pix
Maybe I must upgrade 2501 softwareor pix software?

Thank you

Now I see, the problem you have is still a routing issue.

You can leave the server's default gateway pointing at the PIX 172.20.1.254.

Add a route in the PIX:
route inside 172.22.0.0 255.255.0.0 172.20.n.n

Where n.n is the IP address of your router on the 172.20.0.0 subnet.

However a better way to set the routing would be:

1 Servers D/F point at cisco router 172.20.n.n,

2 PIX route to 172.22.0.0 points at Cisco router,

3 Cisco router 172.20.n.n D/F route points to PIX,

4 Cisco router 172.20.n.n has D/F route pointing to 172.30.n.n on the 172.20.n.n router.

Thank

But what you mean D/F ?
Default gateway?

At Cisco 2501 router 172.20.1.254 there are:
show ip route
172.20.22.0/24 [1/0] via 172.20.1.83
172.20.0.0/16 is directly connecte Serial0
subnets, 2 masks
3
.22.0.0/24 is subnetted, 1 subnets
172.22.1.0 [1/0] via 172.30.1.253

At pix firewall there are :
route dmz1 172.22.1.0 255.255.255.0 172.20.1.254
But it let ping from 172.22.x.x subnet only pix firewall itself

thank
