TCP/IP - X25

Good morning Folks,

I have this situation

PC1 -> router A - router B -> pc2

where:

PC1=192.168.1.1

router A (eth)=192.168.1.100

router A (serial) = x25 123

router B (serial) = x25 789

router B (eth) = 192.168.2.100

PC2= 192.168.2.1

Now I can use a "translate" and start a telnet session from pc1 to router B, but what I need is start a telnet session from pc1 to pc2.

What I have to do? a translate on route B? How?

Thanks

Re: TCP/IP - X25

I need TCP over X25.

About the file attached, I can connect from PC A to router B, and I can connect from router A to PC B, but I can't connect from pc A to pc B. (I'm using apache for this test)

that is my routers configurations:

show conf

Re: TCP/IP - X25

I got it!, but when I open my page it came with tcp header too, not the correct page.

Is it a problem of encapsulation? How can I resolve this?

Re: TCP/IP - X25

here is an example to route TCP/IP over x25 network:

!

interface Ethernet0

ip address 194.147.160.254 255.255.255.0

!

interface Serial0

ip address 192.1.1.1 255.255.255.0

encapsulation x25

x25 address 133014389

x25 htc 2

x25 idle 1

x25 nvc 2

x25 map ip 192.1.1.2 112010132

(remote wan) (remote x25)

!

ip route 193.1.1.0 255.255.255.0 192.1.1.2
