Re: SNA DLC through PIX 515

The PIX only passes IP traffic, and even then only unicast traffic (no broadcasts or multicasts (multicasts can be passed in 6.2 code actually).

If your SNA traffic is encapsulated in an IP packet using DLSw or GRE tunneling or the like then yes, the PIX should pass it. If it's just a straight DLC SNA packet then no, the PIX will not pass it.
