No need to apologise for not knowing. We all have to learn. Asking questions and showing your efforts is great. I hope that someone can help you as I'm guessing it's not working given that you are asking the question.
You are right that both ends will need to know how to send packets to the other, unless you are using UDP. The more usual TCP is a bit like sending a parcel with recorded-delivery so an acknowledgement is returned by the receiver. Using UDP is more like just sending a postcard and hoping from a holiday abroad it gets there.
I have two questions initially:-
- Do you have a default route/gateway for all the traffic without a match in your list?
- Can you give us the output from netstat -rn on server A too please?
Thanks, in advance,
Robin

srtconfig
SRTCONFIG(1) BSD General Commands Manual SRTCONFIG(1)
NAME
srtconfig -- configure srt interfaces
SYNOPSIS
srtconfig srtX
srtconfig srtX N
srtconfig srtX del N
srtconfig srtX add srcaddr mask dstif dstaddr
srtconfig srtX set N srcaddr mask dstif dstaddr
DESCRIPTION
srtconfig configures, or queries the configuration of, srt(4) interfaces. An srt(4) interface parcels packets out to other interfaces based
on their source addresses (the normal routing mechanisms handle routing decisions based on destination addresses). An interface may have any
number of routing choices; they are examined in order until one matching the packet is found. The packet is sent to the corresponding inter-
face. (Any interface, even another srt interface, may be specified; if the configurations collaborate to cause a packet to loop forever, the
system will lock up or crash.)
When run with only one argument, srtconfig prints the settings for the specified interface.
When run with two arguments, srtconfig prints the settings for the routing choice whose number is given as the second argument.
The form with 'del' deletes a routing choice, identified by its number. Other choices with higher numbers, if any, will be renumbered
accordingly.
The 'add' form adds a choice; the other arguments describe it, and are documented below. The new choice is added at the end of the list.
The 'set' form replaces an existing choice, given its number. The other arguments describe the new choice which is to replace whatever cur-
rently exists at the given number N.
A choice is described by four pieces of information: a source address and mask, which are used to determine which choice an outgoing packet
uses, a destination interface, and a destination address for the new interface. The source address and mask are specified like any Internet
addresses (for convenience, the mask may instead be specified as a '/' followed by a small integer, CIDR-style; note that in this case the
mask must still be a separate argument; it cannot be appended to the end of the source address argument).
Each srt interface also has ordinary source and destination addresses which are set with ifconfig(8) like any other interface; these should
not be confused with any of the above.
