Disclosed herein are methods and systems for maintaining routing tables in an ad-hoc wireless network. In an embodiment, a first node receives, from a second node having a second network address, a first data packet having a third network address as the source address and a fourth network address as the destination address. The first node determines that its server routing table (i) contains a stored server route to the fourth network address and (ii) does not contain a server route to the third network address, and responsively adds, to its server-to-client routing table, a server-to-client route to the third network address with the second network address as the associated next hop. The first node transmits, to the second node at the second network address, a second data packet that has the third network address as the destination address.
