I have the following statement in an ACL on a customer's border router:
10 permit tcp any any established (48131145 matches)
I was curious if there was any opportunity to write a similar rule for udp, or whether writing a rule that uses "established" for UDP was even valid..
I am not sure about this in light of the fact that TCP is connection oriented, this is what I thought when the ACL statement uses the verbage "established". It was my idea that this may not be able to be written for UDP since it is connectionless, and therefore probably does not establish anything with respect to sessions.
Any input would be welcome.
