Improve security on x25 access over pubblic network

[stefano-dean]

Hi to all,

I'm working with old systems which have transactions with partners over x25 pubblic network.

Partners----->x25.pubblic.Net---->My.routers---->Our.server

Transactions are encrypted at application layer but I wolud restrict access only at some x121 address with our servers; solutions:

1) x29 access-list: are not a solutions it's only to permit o deny access to the routers

2) x25 route .... clear: it's possible matching the source?

Other ideas or experience?

Thanks you

Stefano

Hi Stefano

Talk to your X25 supplier and ask for a CUG (Closed user group).
