translate tcp to x25

hio, I`ve a problem with my tcp to x25 conversation. my client works with tcp. it communites with a x25 server. I put a router to the networks witch makes the protocol translation.the tcp handshake works well, but after the handshake the router sends a 12 byte data pattern to the client. I think the datapattern are control data. The client has problem with this pattern and sends a reset to the client. Is it posible to supress this data packet with 12 byte lenght.

the configuration:

x29 inviteclear-time none


x29 profile POST 1:0 2:0 3:0 4:2 5:0 6:0 7:0 8:0 9:0 10:0

x25 routing

interface Serial1/0

no ip address

encapsulation x25

x25 address 46437055

x25 htc 5

x25 ips 256

x25 ops 256

x25 idle 5

serial restart-delay 0

lapb T1 1600

lapb N2 9

no clns route-cache

translate tcp port 8054 x25 464113482 profile POST quiet swap

x25 route 464113482 interface Serial1/0

thanks for help

Re: translate tcp to x25

I have the same problem. The X25 device don?t accept a call with "pad" pattern, and is impossible to modify the CUD.

Do you have an idea to resolve this?

Best regards.
